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…
Identifying RR Lyrae Variable Stars in Six Years of the Dark Energy Survey
K. M. Stringer, A. Drlica-Wagner, L. Macri +67
We present a search for RR Lyrae stars using the full six-year data set from the Dark Energy Survey (DES) covering ~5,000 sq. deg. of the southern sky. Using a multi-stage multi-va…
Probing galaxy evolution in massive clusters using ACT and DES: splashback as a cosmic clock
Susmita Adhikari, Tae-hyeon Shin, Bhuvnesh Jain +113
We measure the projected number density profiles of galaxies and the splashback feature in clusters selected by the Sunyaev--Zeldovich (SZ) effect from the Advanced Atacama Cosmolo…
Discovery of a Candidate Binary Supermassive Black Hole in a Periodic Quasar from Circumbinary Accretion Variability
Wei-Ting Liao, Yu-Ching Chen, Xin Liu +68
Binary supermassive black holes (BSBHs) are expected to be a generic byproduct from hierarchical galaxy formation. The final coalescence of BSBHs is thought to be the loudest gravi…
Dust Reverberation Mapping in Distant Quasars from Optical and Mid-Infrared Imaging Surveys
Qian Yang, Yue Shen, Xin Liu +47
The size of the dust torus in Active Galactic Nuclei (AGN) and their high-luminosity counterparts, quasars, can be inferred from the time delay between UV/optical accretion disk co…
Shadows in the Dark: Low-Surface-Brightness Galaxies Discovered in the Dark Energy Survey
D. Tanoglidis, A. Drlica-Wagner, K. Wei +67
We present a catalog of 23,790 extended low-surface-brightness galaxies (LSBGs) identified in from the first three years of imaging data from the Dark Energy Survey…
The Diffuse Light Envelope of Luminous Red Galaxies
Y. Leung, Y. Zhang, B. Yanny +53
We use a stacking method to study the radial light profiles of luminous red galaxies (LRGs) at redshift and , out to a radial range of 200 kpc. We do not fin…
The Host Galaxies of Rapidly Evolving Transients in the Dark Energy Survey
P. Wiseman, M. Pursiainen, M. Childress +72
Rapidly evolving transients (RETs), also termed fast blue optical transients (FBOTs), are a distinct class of astrophysical event. They are characterised by lightcurves that declin…
A Deeper Look at DES Dwarf Galaxy Candidates: Grus I and Indus II
Sarah A. Cantu, Andrew B. Pace, Jennifer Marshall +11
We present deep - and -band Magellan/Megacam photometry of two dwarf galaxy candidates discovered in the Dark Energy Survey (DES), Grus I and Indus II (DES J2038-4609). For t…
Is diffuse intracluster light a good tracer of the galaxy cluster matter distribution?
H. Sampaio-Santos, Y. Zhang, R. L. C. Ogando +64
We explore the relation between diffuse intracluster light (central galaxy included) and the galaxy cluster (baryonic and dark) matter distribution using a sample of 528 clusters a…
A joint SZ-Xray-optical analysis of the dynamical state of 288 massive galaxy clusters
A. Zenteno, D. Hernández-Lang, M. Klein +75
We use imaging from the first three years of the Dark Energy Survey to characterize the dynamical state of 288 galaxy clusters at detected in the Sout…
STRIDES: Spectroscopic and photometric characterization of the environment and effects of mass along the line of sight to the gravitational lenses DES J0408-5354 and WGD 2038-4008
E. J. Buckley-Geer, H. Lin, C. Rusu +65
In time-delay cosmography, three of the key ingredients are 1) determining the velocity dispersion of the lensing galaxy, 2) identifying galaxies and groups along the line of sight…
The impact of spectroscopic incompleteness in direct calibration of redshift distributions for weak lensing surveys
W. G. Hartley, C. Chang, S. Samani +74
Obtaining accurate distributions of galaxy redshifts is a critical aspect of weak lensing cosmology experiments. One of the methods used to estimate and validate redshift distribut…
The Curious Case of PHL 293B: A Long-Lived Transient in a Metal-Poor Blue Compact Dwarf Galaxy
Colin J. Burke, Vivienne F. Baldassare, Xin Liu +51
We report on small-amplitude optical variability and recent dissipation of the unusually persistent broad emission lines in the blue compact dwarf galaxy PHL 293B. The galaxy's unu…
Supernova Host Galaxies in the Dark Energy Survey: I. Deep Coadds, Photometry, and Stellar Masses
P. Wiseman, M. Smith, M. Childress +75
The five-year Dark Energy Survey supernova programme (DES-SN) is one of the largest and deepest transient surveys to date in terms of volume and number of supernovae. Identifying a…
