SPECULATOR: Emulating stellar population synthesis for fast and accurate galaxy spectra and photometry
Justin Alsing, Hiranya Peiris, Joel Leja +6
We present SPECULATOR - a fast, accurate, and flexible framework for emulating stellar population synthesis (SPS) models for predicting galaxy spectra and photometry. For emulating…
Predicting fully self-consistent satellite richness, galaxy growth and starformation rates from the STastical sEmi-Empirical modeL STEEL
Philip J. Grylls, F. Shankar, J. Leja +4
Observational systematics complicate comparisons with theoretical models limiting understanding of galaxy evolution. In particular, different empirical determinations of the stella…
A New Census of the 0.2 < z < 3.0 Universe, Part I: The Stellar Mass Function
Joel Leja, Joshua S. Speagle, Benjamin D. Johnson +3
There has been a long-standing factor-of-two tension between the observed star formation rate density and the observed stellar mass buildup after . Recently we have propose…
Lick Observatory Supernova Search Follow-Up Program: Photometry Data Release of 93 Type Ia Supernovae
Benjamin E. Stahl, WeiKang Zheng, Thomas de Jaeger +52
We present BVRI and unfiltered light curves of 93 Type Ia supernovae (SNe Ia) from the Lick Observatory Supernova Search (LOSS) follow-up program conducted between 2005 and 2018. O…
The Hubble Legacy Field GOODS-S Photometric Catalog
Katherine E. Whitaker, Mohammad Ashas, Garth Illingworth +12
This manuscript describes the public release of the Hubble Legacy Fields (HLF) project photometric catalog for the extended GOODS-South region from the Hubble Space Telescope (HST)…
Model-independent constraints on the hydrogen-ionizing emissivity at z>6
Charlotte A. Mason, Rohan P. Naidu, Sandro Tacchella +1
Modelling reionization often requires significant assumptions about the properties of ionizing sources. Here, we infer the total output of hydrogen-ionizing photons (the ionizing e…
