The Outer Stellar Mass of Massive Galaxies: A Simple Tracer of Halo Mass with Scatter Comparable to Richness and Reduced Projection Effects
Song Huang, Alexie Leauthaud, Christopher Bradshaw +7
Using the weak gravitational lensing data from the Hyper Suprime-Cam Subaru Strategic Program (HSC survey), we study the potential of different stellar mass estimates in tracing ha…
Generating Synthetic Cosmological Data with GalSampler
Andrew Hearin, Danila Korytov, Eve Kovacs +4
As part of the effort to meet the needs of the Large Synoptic Survey Telescope Dark Energy Science Collaboration (LSST DESC) for accurate, realistically complex mock galaxy catalog…
Galaxy-Galaxy Lensing in HSC: Validation Tests and the Impact of Heterogeneous Spectroscopic Training Sets
Joshua S. Speagle, Alexie Leauthaud, Song Huang +9
Although photometric redshifts (photo-z's) are crucial ingredients for current and upcoming large-scale surveys, the high-quality spectroscopic redshifts currently available to tra…
Physical Correlations of the Scatter between Galaxy Mass, Stellar Content, and Halo Mass
Christopher Bradshaw, Alexie Leauthaud, Andrew Hearin +2
We use the UniverseMachine to analyze the source of scatter between the central galaxy mass, the total stellar mass in the halo, and the dark matter halo mass. We also propose a ne…
Weak Lensing Reveals a Tight Connection Between Dark Matter Halo Mass and the Distribution of Stellar Mass in Massive Galaxies
Song Huang, Alexie Leauthaud, Andrew Hearin +9
Using deep images from the Hyper Suprime-Cam (HSC) survey and taking advantage of its unprecedented weak lensing capabilities, we reveal a remarkably tight connection between the s…
Predictions for Observing Protostellar Outflows with ALMA
C. Bradshaw, S. S. R. Offner, H. G. Arce
Protostellar outflows provide a means to probe the accretion process of forming stars and their ability to inject energy into their surroundings. However, conclusions based on outf…
