HET Publication Report HET Board Meeting 3/4 December 2020 Zoom Land HET Publication Report HET Board Meeting 3/4 December 2020 Zoom Land 1 Executive Summary • There are now 420 peer-reviewed HET publications – Fifteen papers published in 2019 – As of 27 November, nineteen published papers in 2020 • HET papers have 29363 citations – Average of 70, median of 39 citations per paper – H-number of 90 – 81 papers have ≥ 100 citations; 175 have ≥ 50 cites • Wide angle surveys account for 26% of papers and 35% of citations. • Synoptic (e.g., planet searches) and Target of Opportunity (e.g., supernovae and γ-ray bursts) programs have produced 47% of the papers and 47% of the citations, respectively. • Listing of the HET papers (with ADS links) is given at http://personal.psu.edu/dps7/hetpapers.html 2 HET Program Classification Code TypeofProgram Examples 1 ToO Supernovae,Gamma-rayBursts 2 Synoptic Exoplanets,EclipsingBinaries 3 OneorTwoObjects HaloofNGC821 4 Narrow-angle HDF,VirgoCluster 5 Wide-angle BlazarSurvey 6 HETTechnical HETQueue 7 HETDEXTheory DarkEnergywithBAO 8 Other HETOptics Programs also broken down into “Dark Time”, “Light Time”, and “Other”. 3 Peer-reviewed Publications • There are now 420 journal papers that either use HET data or (nine cases) use the HET as the motivation for the paper (e.g., technical papers, theoretical studies). • Except for 2005, approximately 22 HET papers were published each year since 2002 through the shutdown. A record 44 papers were published in 2012. • In 2020 a total of fifteen HET papers appeared; nineteen have been published to date in 2020. • Each HET partner has published at least 14 papers using HET data. • Nineteen papers have been published from NOAO time. • A total of 28 SDSS SNe papers have appeared in print. (The final data release paper appeared in early 2018). • A total of 29 publications with new instrumentation (LRS2/HPF/VIRUS). A listing of the HET papers (with ADS links) is given at http://personal.psu.edu/dps7/hetpapers.html 4 Citations to Peer-reviewed Publications • The 420 HET papers have garnered 29363 citations for an average of 69.9 per paper (median number is 39). • The HET’s H-number is now 90. • The number of citations ranges from 0 to 1190. Eleven papers have one or zero citations; 175 have 50 or more citations. • Approximately 35% of the HET citations are produced by “Wide angle” surveys (the primary science program for the “SST”). This fraction continues to slowly decrease. • The four most cited Wide Angle Survey papers have 436, 531, 666, and 706 citations. • “Dark Time” projects have average higher citation rates (87) than “Light Time” programs (48). The 2:1 ratio has remained reasonably constant over time, although the ratio has been steadily decreasing. • The synoptic programs (primarily planet searches) are a significant component of both the number of publications and citations (top four papers have 235, 251, 272, and 417 citations). • “Target of Opportunity” impact: Top four ToO papers have 367, 406, 554, and 1190 citations. • The SDSS Supernova Survey (HET played key role in obtaining spectra of the faintest targets) produced an average of 151 citations per paper, as well as the highest-cited work (1190 citations from 2014 publication). 5 Summary of HET Publications November 2020 Total Average Year Papers Total Citations Citations 2000 9 9 582 64.67 2001 13 22 1351 103.92 2002 10 32 1061 106.10 2003 20 52 1664 83.20 2004 21 73 1553 73.95 2005 7 80 642 91.71 2006 21 101 1687 80.33 2007 21 122 2045 97.38 2008 24 146 2898 120.75 2009 26 172 2904 111.69 2010 33 205 2486 75.33 2011 26 231 2218 85.31 2012 44 275 3032 68.91 2013 23 298 731 31.78 2014 24 322 2211 92.12 2015 28 350 1040 37.14 2016 19 369 655 34.47 2017 8 377 140 17.50 2018 9 386 262 29.11 2019 15 401 136 9.07 2020 19 420 65 3.42 Total 420 29363 69.91 6 Summary of Program Classes Total Average Code Class Papers Citations Citations 1 ToO 80 7813 97.66 2 Synoptic 116 6104 52.62 3 SingleObject 66 2768 41.94 4 PencilBeam 35 2220 63.43 5 WideAngle 111 10140 91.35 6 Technical 7 255 36.43 7 HETDEX 3 47 15.67 8 Other 2 16 8.00 Summary of Dark/Light Time Total Average Code Time Papers Citations Citations 1 Dark 239 20827 87.14 2 Light 172 8267 48.06 3 Other 9 269 29.89 7 HET Publications Sorted by Journal Average Papers Citations Journal 77 78.18 TheAstronomicalJournal 172 67.70 TheAstrophysicalJournal 32 59.00 TheAstrophysicalJournal(Letters) 13 49.92 ThePublicationsoftheA.S.P. 18 130.06 The AstrophysicalJournal SupplementSeries 9 206.33 Nature 1 235.00 Science 41 34.07 M.N.R.A.S. 2 31.00 M.N.R.A.S.(Letters) 45 65.56 AstronomyandAstrophysics 5 34.20 AstronomyandAstrophysics(Letters) 1 17.00 J.C.A.P. 1 97.00 OpticsExpress 1 4.00 AstronomischeNachrichten 1 3.00 J.A.T.I.S. 1 27.00 Optica 8 HET Publications Sorted by Instrument Total Average Code Instrument Papers Citations Citations 1 None 6 236 39.33 2 LRS 226 20606 91.18 3 MRS 1 19 19.00 4 HRS 156 8189 52.49 5 UFOE 2 110 55.00 6 LRS2 16 129 8.06 7 HPF 12 74 6.17 8 VIRUS 1 0 0.00 9 “Hot Papers” (2017-2020) (133) The Data Release of the Sloan Digital Sky Survey-II Supernova Survey.

  • Lurking in the Shadows: Wide-Separation Gas Giants As Tracers of Planet Formation
    Lurking in the Shadows: Wide-Separation Gas Giants as Tracers of Planet Formation Thesis by Marta Levesque Bryan In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California 2018 Defended May 1, 2018 ii © 2018 Marta Levesque Bryan ORCID: [0000-0002-6076-5967] All rights reserved iii ACKNOWLEDGEMENTS First and foremost I would like to thank Heather Knutson, who I had the great privilege of working with as my thesis advisor. Her encouragement, guidance, and perspective helped me navigate many a challenging problem, and my conversations with her were a consistent source of positivity and learning throughout my time at Caltech. I leave graduate school a better scientist and person for having her as a role model. Heather fostered a wonderfully positive and supportive environment for her students, giving us the space to explore and grow - I could not have asked for a better advisor or research experience. I would also like to thank Konstantin Batygin for enthusiastic and illuminating discussions that always left me more excited to explore the result at hand. Thank you as well to Dimitri Mawet for providing both expertise and contagious optimism for some of my latest direct imaging endeavors. Thank you to the rest of my thesis committee, namely Geoff Blake, Evan Kirby, and Chuck Steidel for their support, helpful conversations, and insightful questions. I am grateful to have had the opportunity to collaborate with Brendan Bowler. His talk at Caltech my second year of graduate school introduced me to an unexpected population of massive wide-separation planetary-mass companions, and lead to a long-running collaboration from which several of my thesis projects were born.

Gueorguiev 2,3 1 Geneva Observatory, University of Geneva, chemin des Maillettes 51, CH-1290 Sauverny, Switzerland 2 Institute for Advanced Physical Studies, Montevideo Street, Sofia 1618, Bulgaria; [email protected] 3 Ronin Institute for Independent Scholarship, 127 Haddon Pl., Montclair, NJ 07043, USA * Correspondence: [email protected] Received: 7 February 2020; Accepted: 9 March 2020; Published: 18 March 2020 Abstract: The Scale Invariant Vacuum (SIV) theory rests on the basic hypothesis that the macroscopic empty space is scale invariant. This hypothesis is applied in the context of the Integrable Weyl Geometry, where it leads to considerable simplifications in the scale covariant cosmological equations. After an initial explosion and a phase of braking, the cosmological models show a continuous acceleration of the expansion. Several observational tests of the SIV cosmology are performed: on the relation between H0 and the age of the Universe, on the m − z diagram for SNIa data and its extension to z = 7 with quasars and GRBs, and on the H(z) vs. z relation. All comparisons show a very good agreement between SIV predictions and observations. Predictions for the future observations of the redshift drifts are also given. In the weak field approximation, the equation of motion contains, in addition to the classical Newtonian term, an acceleration term (usually very small) depending on the velocity. The two-body problem is studied, showing a slow expansion of the classical conics. The new equation has been applied to clusters of galaxies, to rotating galaxies (some proximities with Modifies Newtonian Dynamics, MOND, are noticed), to the velocity dispersion vs.

In this work we derive new precise and homogeneous parameters for 37 stars with planets. For this purpose, we analyze high resolution spectra obtained by the NARVAL spectrograph for a sample composed of bright planet host stars in the northern hemisphere. The new parameters are included in the SWEET-Cat online catalogue. Methods. To ensure that the catalogue is homogeneous, we use our standard spectroscopic analysis procedure, ARES+MOOG, to derive effective temperatures, surface gravities, and metallicities. These spectroscopic stellar parameters are then used as input to compute the stellar mass and radius, which are fundamental for the derivation of the planetary mass and radius.

  • Luminosity - Wikipedia
    12/2/2018 Luminosity - Wikipedia Luminosity In astronomy, luminosity is the total amount of energy emitted by a star, galaxy, or other astronomical object per unit time.[1] It is related to the brightness, which is the luminosity of an object in a given spectral region.[1] In SI units luminosity is measured in joules per second or watts. Values for luminosity are often given in the terms of the luminosity of the Sun, L⊙. Luminosity can also be given in terms of magnitude: the absolute bolometric magnitude (Mbol) of an object is a logarithmic measure of its total energy emission rate. Contents Measuring luminosity Stellar luminosity Image of galaxy NGC 4945 showing Radio luminosity the huge luminosity of the central few star clusters, suggesting there is an Magnitude AGN located in the center of the Luminosity formulae galaxy. Magnitude formulae See also References Further reading External links Measuring luminosity In astronomy, luminosity is the amount of electromagnetic energy a body radiates per unit of time.[2] When not qualified, the term "luminosity" means bolometric luminosity, which is measured either in the SI units, watts, or in terms of solar luminosities (L☉). A bolometer is the instrument used to measure radiant energy over a wide band by absorption and measurement of heating. A star also radiates neutrinos, which carry off some energy (about 2% in the case of our Sun), contributing to the star's total luminosity.[3] The IAU has defined a nominal solar luminosity of 3.828 × 102 6 W to promote publication of consistent and comparable values in units of https://en.wikipedia.org/wiki/Luminosity 1/9 12/2/2018 Luminosity - Wikipedia the solar luminosity.[4] While bolometers do exist, they cannot be used to measure even the apparent brightness of a star because they are insufficiently sensitive across the electromagnetic spectrum and because most wavelengths do not reach the surface of the Earth.

Ruchti1 1 Max-Planck Institute for Astrophysics, Karl-Schwarzschild Str. 1, 85741 Garching, Germany e-mail: [email protected] 2 Landessternwarte, Königstuhl 12, 69117 Heidelberg, Germany 3 Department of Physics, Western Michigan University, Kalamazoo, MI 49008, USA Received 13 April 2012 / Accepted 5 July 2012 ABSTRACT We investigate the statistical equilibrium of neutral and singly-ionized strontium in late-type stellar atmospheres. Particular attention is given to the completeness of the model atom, which includes new energy levels, transition probabilities, photoionization and electron-impact excitation cross-sections computed with the R-matrix method. The NLTE model is applied to the analysis of Sr I and Sr II lines in the spectra of the Sun, Procyon, Arcturus, and HD 122563, showing a significant improvement in the ionization balance compared to LTE line formation calculations, which predict abundance discrepancies of up to 0.5 dex. The solar Sr abundance is log = 2.93 ± 0.04 dex, in agreement with the meteorites. We present the grid of NLTE abundance corrections for Sr I and Sr II lines that covers a wide range of stellar parameters. Key words. atomic data – line: formation – radiative transfer – Sun: abundances – stars: abundances – stars: atmospheres 1.

  • Jet-Induced Star Formation in 3C 285 and Minkowski's Object⋆
    A&A 574, A34 (2015) Astronomy DOI: 10.1051/0004-6361/201424932 & c ESO 2015 Astrophysics Jet-induced star formation in 3C 285 and Minkowski’s Object? Q. Salomé, P. Salomé, and F. Combes LERMA, Observatoire de Paris, CNRS UMR 8112, 61 avenue de l’Observatoire, 75014 Paris, France e-mail: [email protected] Received 5 September 2014 / Accepted 6 November 2014 ABSTRACT How efficiently star formation proceeds in galaxies is still an open question. Recent studies suggest that active galactic nucleus (AGN) can regulate the gas accretion and thus slow down star formation (negative feedback). However, evidence of AGN positive feedback has also been observed in a few radio galaxies (e.g. Centaurus A, Minkowski’s Object, 3C 285, and the higher redshift 4C 41.17). Here we present CO observations of 3C 285 and Minkowski’s Object, which are examples of jet-induced star formation. A spot (named 3C 285/09.6 in the present paper) aligned with the 3C 285 radio jet at a projected distance of ∼70 kpc from the galaxy centre shows star formation that is detected in optical emission. Minkowski’s Object is located along the jet of NGC 541 and also shows star formation. Knowing the distribution of molecular gas along the jets is a way to study the physical processes at play in the AGN interaction with the intergalactic medium. We observed CO lines in 3C 285, NGC 541, 3C 285/09.6, and Minkowski’s Object with the IRAM 30 m telescope. In the central galaxies, the spectra present a double-horn profile, typical of a rotation pattern, from which we are able to estimate the molecular gas density profile of the galaxy.
