An Older, More Quiescent Universe from Panchromatic SED Fitting of the 3D-HST Survey
Joel Leja, Benjamin D. Johnson, Charlie Conroy +8
Galaxy observations are influenced by many physical parameters: stellar masses, star formation rates (SFRs), star formation histories (SFHs), metallicities, dust, black hole activi…
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…
Towards a radially-resolved semi-analytic model for the evolution of disc galaxies tuned with machine learning
John C. Forbes, Mark R. Krumholz, Joshua S. Speagle
We present a flexible, detailed model for the evolution of galactic discs in a cosmological context since , including a physically-motivated model for radial transport…
Cosmology from cosmic shear power spectra with Subaru Hyper Suprime-Cam first-year data
Chiaki Hikage, Masamune Oguri, Takashi Hamana +34
We measure cosmic weak lensing shear power spectra with the Subaru Hyper Suprime-Cam (HSC) survey first-year shear catalog covering 137deg of the sky. Thanks to the high effect…
Mapping Distances Across the Perseus Molecular Cloud Using CO Observations, Stellar Photometry, and Gaia DR2 Parallax Measurements
Catherine Zucker, Edward F. Schlafly, Joshua S. Speagle +4
We present a new technique to determine distances to major star-forming regions across the Perseus Molecular Cloud, using a combination of stellar photometry, astrometric data, and…
