Unraveling the complex structure of AGN-driven outflows: V. Integral-field spectroscopy of 40 moderate-luminosity Type-2 AGNs
Rongxin Luo, Jong-Hak Woo, Marios Karouzos +6
There is an ongoing debate on whether feedback from active galactic nuclei (AGNs) can effectively regulate the star formation activities in their host galaxies. To investigate the…
Anomaly Detection in Astronomical Images with Generative Adversarial Networks
Kate Storey-Fisher, Marc Huertas-Company, Nesar Ramachandra +4
We present an anomaly detection method using Wasserstein generative adversarial networks (WGANs) on optical galaxy images from the wide-field survey conducted with the Hyper Suprim…
A search for dust and molecular gas in enormous Ly nebulae at
Roberto Decarli, Fabrizio Arrigoni-Battaia, Joseph F. Hennawi +3
Enormous Ly nebulae, extending over 300-500\,kpc around quasars, represent the pinnacle of galaxy and cluster formation. Here we present IRAM Plateau de Bure Interferometer obse…
The Massive M31 Cluster G1: Detailed Chemical Abundances from Integrated Light Spectroscopy
Charli M. Sakari, Matthew D. Shetrone, Andrew McWilliam +1
G1, also known as Mayall II, is one of the most massive star clusters in M31. Its mass, ellipticity, and location in the outer halo make it a compelling candidate for a former nucl…
An Extended Halo-based Group/Cluster finder: application to the DESI legacy imaging surveys DR8
Xiaohu Yang, Haojie Xu, Min He +20
We extend the halo-based group finder developed by \citet[][]{Yang2005a} to use data {\it simultaneously} with either photometric or spectroscopic redshifts. A mock galaxy redshift…
A High-Resolution View of Fast Radio Burst Host Environments
Alexandra G. Mannings, Wen-fai Fong, Sunil Simha +11
We present Hubble Space Telescope (HST/WFC3) ultraviolet and infrared observations of eight fast radio burst (FRB) host galaxies with sub-arcsecond localizations, including the hos…
Compaction-Driven Black Hole Growth
Sharon Lapiner, Avishai Dekel, Yohan Dubois
We study the interplay between galaxy evolution and central black-hole (BH) growth using the {NewHorizon} cosmological simulation. BH growth is slow when the dark-matter halo is be…
Hubble Space Telescope Observations of Two Faint Dwarf Satellites of Nearby LMC Analogs from MADCASH
Jeffrey L. Carlin, Burcin Mutlu-Pakdil, Denija Crnojevic +11
We present a deep Hubble Space Telescope (HST) imaging study of two dwarf galaxies in the halos of Local Volume Large Magellanic Cloud (LMC) analogs. These dwarfs were discovered a…
Pushing automated morphological classifications to their limits with the Dark Energy Survey
J. Vega-Ferrero, H. Domínguez Sánchez, M. Bernardi +60
We present morphological classifications of 27 million galaxies from the Dark Energy Survey (DES) Data Release 1 (DR1) using a supervised deep learning algorithm. The classif…
A machine learning approach to galaxy properties: joint redshift-stellar mass probability distributions with Random Forest
S. Mucesh, W. G. Hartley, A. Palmese +72
We demonstrate that highly accurate joint redshift-stellar mass probability distribution functions (PDFs) can be obtained using the Random Forest (RF) machine learning (ML) algorit…
Orbital Torus Imaging: Using Element Abundances to Map Orbits and Mass in the Milky Way
Adrian M. Price-Whelan, David W. Hogg, Kathryn V. Johnston +9
Many approaches to galaxy dynamics assume that the gravitational potential is simple and the distribution function is time-invariant. Under these assumptions there are traditional…
The COS Absorption Survey of Baryon Harbors: Unveiling the Physical Conditions of Circumgalactic Gas through Multiphase Bayesian Ionization Modeling
Karl J. Haislmaier, Todd M. Tripp, Neal Katz +4
Quasar absorption systems encode a wealth of information about the abundances, ionization structure, and physical conditions in intergalactic and circumgalactic media. Simple (ofte…
The influence of the secular perturbation of an intermediate-mass companion: I. Eccentricity excitation of disk stars at the Galactic center
Xiaochen Zheng, Douglas N. C. Lin, Shude Mao
There is a dense group of OB and Wolf-Rayet stars within a fraction of a parsec from the super-massive black hole (SMBH) at the Galactic Center. These stars appear to be coeval and…
RELICS-DP7: Spectroscopic Confirmation of a Dichromatic Primeval Galaxy at z ~ 7
Debora Pelliccia, Victoria Strait, Brian C. Lemaux +12
We report the discovery of a spectroscopically-confirmed strong Lyman- emitter at , observed as part of the Reionization Cluster Lensing Survey (RELICS). This…
The nature of giant clumps in high-z discs: a deep-learning comparison of simulations and observations
Omri Ginzburg, Marc Huertas-Company, Avishai Dekel +4
We use deep learning to explore the nature of observed giant clumps in high-redshift disc galaxies, based on their identification and classification in cosmological simulations. Si…
SDSS-IV MaNGA: Refining Strong Line Diagnostic Classifications Using Spatially Resolved Gas Dynamics
David R. Law, Xihan Ji, Francesco Belfiore +8
We use the statistical power of the MaNGA integral-field spectroscopic galaxy survey to improve the definition of strong line diagnostic boundaries used to classify gas ionization…
An Amusing Look at the Host of the Periodic Nuclear Transient ASASSN-14ko Reveals a Second AGN
M. A. Tucker, B. J. Shappee, J. T. Hinkle +10
We present Multi-Unit Spectroscopic Explorer (MUSE) integral-field spectroscopy of ESO 253G003, which hosts a known Active Galactic Nucleus (AGN) and the periodic nuclear transi…
Tightly coupled morpho-kinematic evolution for massive star-forming and quiescent galaxies across 7 Gyr of cosmic time
Anna de Graaff, Rachel Bezanson, Marijn Franx +11
