X-rays across the galaxy population: The distribution of AGN accretion rates as a function of stellar mass and redshift

<p>We&nbsp;provide measurements of the probability distribution function of specific black hole&nbsp;accretion rates within a sample of galaxies of a given stellar mass and redshift,&nbsp;<span class="math-tex">\(p(\log \lambda_{sBHAR} | M_*,z)\)</span>. Measurements are provided&nbsp;for all galaxies, star-forming galaxies and quiescent galaxies. We also provide estimates of the AGN duty cycle, <span class="math-tex">\(f(\lambda_{sBHAR} &gt;0.01)\)</span>&nbsp;i.e. the fraction of galaxies with an AGN above a given limit in specific accretion rate, based on the probability distribution functions.&nbsp;Full details are provided in Aird et al. (2018, MNRAS, 474, 1225); please cite this publication if you use these measurements.&nbsp;</p>

Catalog Data for Prior-Informed AGN-Host Spectral Decomposition Using PyQSOFit

<p>This catalog contains 76,565 AGN-host decomposed spectral measurements for all quasars with z&lt;0.8 in SDSS DR16Q. Our prior-informed decomposition method significantly improved the decomposition success rate from less than 60% to 94%. For the first time, we perform the AGN-host spectral decomposition on survey scale catalog.</p> <p>Our spectral decomposition results are highly consistent to those of HSC image decomposition. Our catalog suggests that an average host galaxy contribution at 5100A is 38.8%, which would lead to an overestimation of 0.215 dex in L5100 and 0.219 dex in black hole mass if the host is not removed. The Dn4000 and stellar velocity dispersion measurements from the decomposed host galaxy spectra are also provided.</p> <p>Please read this paper for more techinique details: <a href="https://arxiv.org/abs/2406.17598">arXiv: 2406.17598</a></p>

Basic Considerations for the Observability of Kinematically Offset Binary AGN

<p>KDE resampled massive black-hole (MBH) binary&nbsp;population&nbsp;used for the analysis in Kelley 2020, <em>Considerations for the Observability of Kinematically Offset Binary AGN</em> (2005.10255).</p> <p>We start with a population of&nbsp;MBH binaries derived from the Illustris cosmological simulations, and evolved using semi-analytic post-processing models.&nbsp; These methods are described in Kelley et al. 2016 (1606.01900)&nbsp;and Kelley et al. 2017a,b (1702.02180 and&nbsp;1711.00075).&nbsp; We then&nbsp;use the kernel density estimation (KDE) technique to resample this population from the Illustris volume, into a sample of binaries from a full, simulated light-cone of observations.&nbsp; The binaries are resampled in bins of observed orbital period.&nbsp; The number of resampled binaries in a given period bin are restricted to 500,000.&nbsp; When this occurs, the &#39;weight&#39; of those binaries is assigned a value greater than one, while the &#39;weight&#39; of binaries in unrestricted period bins is set to unity.&nbsp; For example, if the &#39;true&#39; number of binaries in a bin should have been 1e6, the number of samples would be restricted to 5e5, and the weight of each of those binaries&nbsp;would be set to 2.0.&nbsp; If the number of binaries in a bin were instead 2e5, which is less than the limit, then each of those binaries&nbsp;is given a weight of 1.0.&nbsp; Only a single realization of this sample is included, but additional realizations can be produced if needed and on request.</p> <p>The data are presented in hdf5 format and contain the following arrays:</p> <pre><code># Meta-Data `periods`: shape: (201,) units: seconds descr: the edges of the bins in observed orbital period from which the population was sampled. `counts`: shape: (200,) units: None descr: The number of binaries produced in each period bin. This number for each bin is capped at 500,000. The sum of these values equals the total number of samples (70622013). # Data In this particular realization of data, the number of sampled binaries is `S = 70622013`. `mtot`: shape: (S,) units: grams descr: the total mass of each binary (`M = M1 + M2`). `mrat`: shape: (S,) units: None descr: The mass ratio of each binary, `q = M2/M1 &lt;= 1.0`, where M2 is the mass of the secondary (lower mass) component. `pobs`: shape: (S,) units: seconds descr: The orbital period of each binary in the observer's rest frame (at redshift, `z = 0`). `redz`: shape: (S,) units: None descr: The redshift of each binary. `weights`: shape: (S,) units: None descr: The number of 'true' binaries (i.e. the number that are expected to occur in this realization of an observed universe) represented by this individual 'sample', and having similar binary parameters.</code></pre> <p>&nbsp;</p>

Coordinates of the low-lying energy Agn isomers and the Agn-Tyr complexes

<p>Noble metal clusters with a size around the Fermi wavelength of electrons display quantum confinement effects and properties such as photoluminescence, two-photon absorption, and second and third-harmonic generation. As a result of these unique features, noble metal clusters are increasingly gaining popularity in optics and catalysis. Being highly reactive, it is standard practice to use capping agents to stabilize them.</p> <p>This dataset contains the structural parameters for the low-lying energy Ag<sub>n</sub> isomers and the Ag<sub>n</sub>-Tyr complexes from n = 3–12, all fully optimized at the B3PW91 functional combined with the def2-TZVP basis set. The structural parameters were obtained using a global search strategy combined with DFT calculations to explore the potential energy surface of clusters of atoms and molecules.</p>

AGN Unification Diagram

<p>Schematic representation of our understanding of AGN in the orientation unified scheme. The type of object seen depends on the viewing angle, whether or not the AGN produces a significant jet (radio loud or radio quiet), and the rate of accretion onto the central SMBH (low or high electromagnetic power).&nbsp;The centre of the schematic shows the typical components of an AGN but we note that the geometry of many of these components are still unknown.&nbsp;Radio-loud objects are generally thought to display bipolar jet emission whereas it is only shown on the radio-loud side here. Note radio-quiet is not the same as radio-silent as many galaxies have low level radio emission, which is not significantly above that expected from star-formation and therefore it is unknown if these host radio jets or not.&nbsp;The upper left and upper right quandrants are commonly referred to as low and high excitation radio galaxies (LERG/HERG) respectively.&nbsp;LERGs are also known as hot mode, radio mode, jet mode, and radiatively inefficient sources, while HERGs are also known as cold mode, quasar mode, radiative mode, and radiatively efficient sources. We include some of the most commonly used names for different classes of AGN including broad line radio galaxy (BLRG), narrow line radio galaxy (NLRG), narrow emission line galaxy (NELG), flat spectrum radio quasar (FSRQ), steep spectrum radio quasar (SSRQ), optically violent variables (OVV), and quasi-stellar objects (QSO).&nbsp;Note that while we separate quasars and QSOs as being radio loud and radio quiet respectively, these names are often used interchangeably.&nbsp;Surrounding the central schematic we show whether a particular combination of power, radio emission, and geometry is expected to produce broad or narrow emission lines, or MIR, radio, X-ray, or gamma-ray emission.&nbsp;The transparency of the colour in each ring corresponds to the increasing strength or prevalence of a particular emission type.</p>

Unified Clumpy AGN Torus Model and X-ray spectrum

There may be a version numberb(diff2, diff3) if multiple iterations were done. These may also have names such as diff2g.fits, diff1s.fits if Gaussian blur or small shifts were done as for vs.fits, vsg.fits files.</p> <p>&quot;flat&quot; denotes that a low-pass spatial filter (such as a large median) has been used to reduce the effects of stray light on a difference image.</p> <p>Toomre.zip includes F510 and V images for those galaxies in the Toomre-sequence sample not included in the SARA data.</p> <p>LongSlit.zip includes reduced two-dimensional spectral data as detailed in the paper. _abs indicates that the data values are calibrated to intensity units (ergs/(cm^2 s Angstrom)) using standard-star observations; otherwise they are in instrumental units. Wavelengths are in Angstroms, in air. Data using the ADAM instrument are prefixed with that string.</p> <p>Tunable.zip includes the results of the MaNGAL and SCORPIO tunable-filter observations. The string &ldquo;5007net&rdquo; denotes that the continuum (&ldquo;cont&rdquo;)&nbsp;has been subtracted; &ldquo;5007&rdquo; by itself marks images including the [O III] line&nbsp; but not yet continuum-subtracted.</p>
