  • Multi-Messenger Observations of a Binary Neutron Star Merger
    DRAFT VERSION OCTOBER 6, 2017 Typeset using LATEX twocolumn style in AASTeX61 MULTI-MESSENGER OBSERVATIONS OF A BINARY NEUTRON STAR MERGER LIGO SCIENTIFIC COLLABORATION,VIRGO COLLABORATION AND PARTNER ASTRONOMY GROUPS (Dated: October 6, 2017) ABSTRACT On August 17, 2017 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB170817A) with a time-delay of 1.7swith respect to the merger ⇠ time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance +8 of 40 8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range− 0.86 to 2.26 M . An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT2017gfo) in NGC 4993 (at 40 Mpc) less ⇠ than 11 hours after the merger by the One-Meter, Two Hemisphere (1M2H) team using the 1-m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over 10 days. Following early non-detections, X-ray and radio emission were discovered at the ⇠ transient’s position 9 and 16 days, respectively, after the merger.

The ensuing explosion, a kilonova, which was observed in the lenticular galaxy NGC 4993, is the first detected electromagnetic counterpart of a gravitational wave event.

The results are 101 detections and 192 useful upper limits in the range from 1036 to 1044 erg s1. For most of the galaxies no X-ray data have been available until now. On the basis of this sample with its full sky coverage, we ®nd no galaxy with an unusually low ¯ux from discrete emitters. Below log LB < 9:2L( the X-ray emission is compatible with being entirely due to discrete sources. Above log LB < 11:2L( no galaxy with only discrete emission is found. We further con®rm earlier ®ndings that Lx is strongly correlated with LB. Over the entire data range the slope is found to be 2:23 60:12. We also ®nd a luminosity dependence of this correlation. Below 1 log Lx 40:5 erg s it is consistent with a slope of 1, as expected from discrete emission.

    Draft version May 26, 2021 Typeset using LATEX twocolumn style in AASTeX631 The Hubble Tension Bites the Dust: Sensitivity of the Hubble Constant Determination to Cepheid Color Calibration Edvard Mortsell,¨ 1 Ariel Goobar,1 Joel Johansson,1 and Suhail Dhawan2 1Oskar Klein Centre, Department of Physics, Stockholm University Albanova University Center 106 91 Stockholm, Sweden 2Institute of Astronomy University of Cambridge Madingley Road Cambridge CB3 0HA United Kingdom ABSTRACT Motivated by the large observed diversity in the properties of extra-galactic extinction by dust, we re- analyse the Cepheid calibration used to infer the local value of the Hubble constant, H0, from Type Ia supernovae. Unlike the SH0ES team, we do not enforce a universal color-luminosity relation to correct the near-IR Cepheid magnitudes. Instead, we focus on a data driven method, where the measured colors of the Cepheids are used to derive a color-luminosity relation for each galaxy individually. We present two different analyses, one based on Wesenheit magnitudes, a common practice in the field that attempts to combine corrections from both extinction and variations in intrinsic colors, resulting in H0 = 66.9 ± 2.5 km/s/Mpc, in agreement with the Planck value. In the second approach, we calibrate using color excesses with respect to derived average intrinsic colors, yielding H0 = 71.8 ± 1.6 km/s/Mpc, a 2.7 σ tension with the value inferred from the cosmic microwave background. Hence, we argue that systematic uncertainties related to the choice of Cepheid color-luminosity cali- bration method currently inhibits us from measuring H0 to the precision required to claim a substantial tension with Planck data.

On 2017 August 17, the Laser Interferometer Gravitational-wave Observa- tory (LIGO) and the Virgo interferometer detected gravitational waves em- anating from a binary neutron star merger, GW170817. Nearly simultane- ously, the Fermi and INTEGRAL telescopes detected a gamma-ray transient, GRB 170817A.

  • National Science Olympiad Astronomy 2019 (Division C) Stellar Evolution in Normal & Starburst Galaxies
    National Science Olympiad Astronomy 2019 (Division C) Stellar Evolution in Normal & Starburst Galaxies NASA Universe of Learning/CXC/NSO https://www.universe-of-learning.org/ http://chandra.harvard.edu/index.html 1 Chandra X-Ray Observatory http://chandra.harvard.edu/edu/olympiad.html 2019 Rules 1. DESCRIPTION: Teams will demonstrate an understanding of stellar evolution in normal & starburst galaxies. A TEAM OF UP TO: 2 APPROXIMATE TIME: 50 minutes 2. EVENT PARAMETERS: Each team is permitted to bring two computers (of any kind) or two 3-ring binders (any size) containing information in any form from any source, or one binder and one computer. The materials must be inserted into the rings (notebook sleeves are permitted). Each team member is permitted to bring a programmable calculator. No internet access is allowed; however teams may access a dedicated NASA data base. 2 2019 Rules 3. THE COMPETITION: Using information which may include Hertzsprung-Russell diagrams, spectra, light curves, motions, cosmological distance equations and relationships, stellar magnitudes and classification, multi-wavelength images (X-ray, UV, optical, IR, radio), charts, graphs, and JS9 imaging analysis software, teams will complete activities and answer questions related to: a. Stellar evolution, including stellar classification, spectral features and chemical composition, luminosity, blackbody radiation, color index and H-R diagram transitions, star formation, Cepheids, RR Lyrae stars, Type Ia & Type II supernovas, neutron stars, pulsars, stellar mass black holes, supermassive black holes, X-ray & gamma-ray binary systems, ultraluminous X-ray sources (ULXs), globular clusters, stellar populations in normal & starburst galaxies, galactic structure and interactions, and gravitational waves.
