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…

The SFR-radius connection: data and implications for wind strength and halo concentration

Lin Lin, S. M. Faber, David C. Koo +26

This paper is one in a series that explores the importance of radius as a second parameter in galaxy evolution. The topic investigated here is the relationship between star formati…

Quenching as a Contest between Galaxy Halos and their Central Black Holes

Zhu Chen, S. M. Faber, David. C. Koo +27

Existing models of galaxy formation have not yet explained striking correlations between structure and star-formation activity in galaxies, notably the sloped and moving boundaries…
