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…

The Dragonfly Wide Field Survey. I. Telescope, Survey Design and Data Characterization

Shany Danieli, Deborah Lokhorst, Jielai Zhang +11

We present a description of the Dragonfly Wide Field Survey (DWFS), a deep photometric survey of a wide area of sky. The DWFS covers 330 in the equatorial GAMA fie…

A Tip of the Red Giant Branch Distance to the Dark Matter Deficient Galaxy NGC1052-DF4 from Deep Hubble Space Telescope Data

Shany Danieli, Pieter van Dokkum, Roberto Abraham +3

Previous studies have shown that the large, diffuse galaxies NGC1052-DF2 and NGC1052-DF4 both have populations of unusually luminous globular clusters as well as a very low dark ma…

The Dragonfly Edge-on Galaxies Survey: Shaping the outer disc of NGC 4565 via accretion

Colleen Gilhuly, David Hendel, Allison Merritt +6

We present extremely deep imaging of the well-known edge-on galaxy NGC 4565 (the "Needle Galaxy"), observed as part of the Dragonfly Edge-on Galaxies Survey. Our imaging traces sta…

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…

A Lower Limit on the Mass of Our Galaxy from the H3 Survey

Dennis Zaritsky, Charlie Conroy, Huanian Zhang +5

The timing argument provides a lower limit on the mass of the Milky Way. We find, using a sample of 32 stars at kpc drawn from the H3 Spectroscopic Survey and mock catalog…
