The Merian Survey: Design, Construction, and Characterization of a Filter Set Optimized to Find Dwarf Galaxies and Measure their Dark Matter Halo Properties with Weak Lensing

Yifei Luo, Alexie Leauthaud, Jenny Greene +28

The Merian survey is mapping 850 degrees of the Hyper Suprime-Cam Strategic Survey Program (HSC-SSP) wide layer with two medium-band filters on the 4-meter Victor M. Bla…

Physical Drivers of Emission Line Diversity of SDSS Seyfert 2s and LINERs After Removal of Contributions by Star Formation

Christopher J. Agostino, Samir Salim, S. M. Faber +6

Ionization sources other than HII regions give rise to the right-hand branch in the standard ([NII]) BPT diagram, populated by Seyfert 2s and LINERs. However, because the majority…

Anomaly detection in Hyper Suprime-Cam galaxy images with generative adversarial networks

Kate Storey-Fisher, Marc Huertas-Company, Nesar Ramachandra +5

The problem of anomaly detection in astronomical surveys is becoming increasingly important as data sets grow in size. We present the results of an unsupervised anomaly detection m…

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…

The Activation of Galactic Nuclei and Their Accretion Rates are Linked to the Star Formation Rates and Bulge-types of Their Host Galaxies

Hassen M. Yesuf, S. M. Faber, David C. Koo +3

We use bulge-type classifications of 809 representative SDSS galaxies by Gadotti (2009) to classify a large sample of galaxies into real bulges (classical or elliptical) and pseudo…

How Accurately Can We Detect the Splashback Radius of Dark Matter Halos and its Correlation With Accretion Rate?

Enia Xhakaj, Benedikt Diemer, Alexie Leauthaud +5

The splashback radius () of dark matter halos has recently been detected using weak gravitational lensing and cross-correlations with galaxies. However, different metho…
