  • Study of the Existence of Active Galactic Nuclei of the Evolution and Disappearance of the Torus Through X-Rays
    Universidad Nacional Autónoma de México Instituto de Radioastronomía y Astrofísica PhD. in Science (Astrophysics) Advance of doctoral project Study of the existence of Active Galactic Nuclei of the evolution and disappearance of the torus through X-rays PRESENTS: Natalia Osorio Clavijo ADVISOR: Dra. Omaira González Martín June 2021 1 Introduction It has been widely accepted that all galaxies with developed bulges, host a super massive black hole (SMBH), which in some cases is being fed by an accretion disk, causing the liberation of energy of orders up to bolometric luminosities L ∼ 1044 erg s−1. The nuclei of galaxies with such phenomenon are known as active galactic nuclei (AGN), and can emit through all the electromagnetic spectrum. According to the standard model (Urry and Padovani, 1995) AGN are composed by several regions apart from the accretion disk. Such regions are made up from clouds of dust and gas, although their formation and evolution are still under debate. Among the components, we find the SMBH, whose mass can be of the 6 10 order of ∼ 10 − 10 M , the accretion disk, which is responsible for the accretion onto the SMBH and most of the energy released. The temperature of this structure places the peak of emission at opti- cal/UV wavelengths. The broad line region (BLR) is placed beyond the accretion disk and is formed by clouds of gas, with speeds of several thousands of km/s (Davidson and Netzer, 1979), producing the broadening of lines emitted in the optical and infrarred range (e.g., Hα,Hβ, the Paschen series, etc.) This region is surrounded by the torus, a region composed by dust that is heated by the accretion disk up to a few 1000 of K, placing the peak of its emission at infrared wavelengths.

Anderson? European Southern Observatory, Karl-Schwarzschild-Str. 2, 85748 Garching b. München, Germany e-mail: [email protected] Received 27 August 2019 / Accepted 23 September 2019 ABSTRACT Assessing the significance and implications of the recently established Hubble tension requires the comprehensive identification, quantification, and mitigation of uncertainties and/or biases affecting H0 measurements. Here, we investigate the previously over- looked distance scale bias resulting from the interplay between redshift and Leavitt laws in an expanding Universe: Redshift-Leavitt bias (RLB). Redshift dilates oscillation periods of pulsating stars residing in supernova-host galaxies relative to periods of identical stars residing in nearby (anchor) galaxies. Multiplying dilated log P with Leavitt Law slopes leads to underestimated absolute magni- tudes, overestimated distance moduli, and a systematic error on H0. Emulating the SH0ES distance ladder, we estimate an associated −1 −1 H0 bias of (0:27 ± 0:01)% and obtain a corrected H0 = 73:70 ± 1:40 km s Mpc . RLB becomes increasingly relevant as distance ladder calibrations pursue greater numbers of ever more distant galaxies hosting both Cepheids (or Miras) and type-Ia supernovae. The measured periods of oscillating stars can readily be corrected for heliocentric redshift (e.g. of their host galaxies) in order to ensure H0 measurements free of RLB. Key words. distance scale – stars: oscillations – stars: variables: Cepheids – stars: variables: general – stars: distances – galaxies: distances and redshifts 1.

  • The Black Hole Mass Function Derived from Local Spiral Galaxies

LACY1,2 Published in The Astrophysical Journal, 789:124 (16pp), 2014 July 10 ABSTRACT We present our determination of the nuclear supermassive black hole mass (SMBH) function for spiral galax- ies in the local universe, established from a volume-limited sample consisting of a statistically complete col- lection of the brightest spiral galaxies in the southern (δ< 0◦) hemisphere. Our SMBH mass function agrees well at the high-mass end with previous values given in the literature. At the low-mass end, inconsistencies exist in previous works that still need to be resolved, but our work is more in line with expectations based on modeling of black hole evolution. This low-mass end of the spectrum is critical to our understanding of the mass function and evolution of black holes since the epoch of maximum quasar activity. A limiting luminos- ity (redshift-independent) distance, DL = 25.4 Mpc (z =0.00572) and a limiting absolute B-band magnitude, MB = −19.12 define the sample. These limits define a sample of 140 spiral galaxies, with 128 measurable pitch angles to establish the pitch angle distribution for this sample. This pitch angle distribution function may be useful in the study of the morphology of late-type galaxies.

  • Diffuse Interstellar Bands in NGC 1448
    Astronomy & Astrophysics manuscript no. sissa October 27, 2018 (DOI: will be inserted by hand later) Diffuse Interstellar Bands in NGC 1448⋆ Jesper Sollerman,1 Nick Cox,2 Seppo Mattila,1 Pascale Ehrenfreund,2,3 Lex Kaper,2 Bruno Leibundgut,4 and Peter Lundqvist1 1 Stockholm Observatory, Department of Astronomy, AlbaNova, SE-106 91 Stockholm, Sweden 2 Astronomical Institute ”Anton Pannekoek”, University of Amsterdam, Kruislaan 403, NL-1098, Netherlands 3 Astrobiology Laboratory, Leiden Institute of Chemistry, P.O.Box 9502, 2300 RA Leiden, Netherlands 4 European Southern Observatory, Karl-Schwarzschild-Strasse 2, Garching, D-85748, Germany Received — ?, Accepted — ? Abstract. We present spectroscopic VLT/UVES observations of two emerging supernovae, the Type Ia SN 2001el and the Type II SN 2003hn, in the spiral galaxy NGC 1448. Our high resolution and high signal-to-noise spectra display atomic lines of Ca , Na , Ti and K in the host galaxy. In the line of sight towards SN 2001el, we also detect over a dozen diffuse interstellar bands (DIBs) within NGC 1448. These DIBs have strengths comparable to low reddening galactic lines of sight, albeit with some variations. In particular, a good match is found with the line of sight towards the σ type diffuse cloud (HD 144217). The DIBs towards SN 2003hn are significantly weaker, and this line of sight has also lower sodium column density. The DIB central velocities show that the DIBs towards SN 2001el are closely related to the strongest interstellar Ca and Na components, indicating that the DIBs are preferentially produced in the same cloud. The ratio of the λ 5797 and λ 5780 DIB strengths (r ∼ 0.14) suggests a rather high UV field in the DIB environment towards SN 2001el.

Diamond-Stanic3, Almudena Alonso-Herrero1,2,4, and George H. Rieke3 Accepted for publication in ApJ on 10 October 2010 ABSTRACT We used Spitzer/IRS spectroscopic data on 426 galaxies including quasars, Seyferts, LINER and H ii galaxies to investigate the relationship among the mid-IR emission lines. There is a tight linear correlation between the [Ne V]14.3 µm and 24.3 µm (97.1 eV) and the [O IV]25.9 µm (54.9 eV) high- ionization emission lines. The correlation also holds for these high-ionization emission lines and the [Ne III]15.56 µm (41 eV) emission line, although only for active galaxies. We used these correlations to calculate the [Ne III] excess due to star formation in Seyfert galaxies. We also estimated the [O IV] luminosity due to star formation in active galaxies and determined that it dominates the [O IV] emission only if the contribution of the active nucleus to the total luminosity is below 5%. We find that the AGN dominates the [O IV] emission in most Seyfert galaxies, whereas star-formation adequately explains the observed [O IV] emission in optically classified H ii galaxies. Finally we computed photoionization models to determine the physical conditions of the narrow line region where these high-ionization lines originate. The estimated ionization parameter range is -2.8 < log U −2 < -2.5 and the total hydrogen column density range is 20 < log nH (cm ) < 21.
