Two Ultra-Faint Milky Way Stellar Systems Discovered in Early Data from the DECam Local Volume Exploration Survey
S. Mau, W. Cerny, A. B. Pace +56
We report the discovery of two ultra-faint stellar systems found in early data from the DECam Local Volume Exploration survey (DELVE). The first system, Centaurus I (DELVE J1238-40…
Uncovering the Orbit of the Hercules Dwarf Galaxy
Alexandra L. Gregory, Michelle L. M. Collins, Denis Erkal +6
We present new chemo--kinematics of the Hercules dwarf galaxy based on Keck II-- DEIMOS spectroscopy. Our 21 confirmed members have a systemic velocity of $v_{\mathrm{Herc}}=46.4\p…
A detailed study of Andromeda XIX, an extreme local analogue of ultra diffuse galaxies
Michelle L. M. Collins, Erik J. Tollerud, R. Michael Rich +5
With a central surface brightness of mag. per sq. arcsec, and half-light radius of ~kpc, Andromeda XIX (And XIX) is an extremely diffuse…
Algorithms and Statistical Models for Scientific Discovery in the Petabyte Era
Brian Nord, Andrew J. Connolly, Jamie Kinney +35
The field of astronomy has arrived at a turning point in terms of size and complexity of both datasets and scientific collaboration. Commensurately, algorithms and statistical mode…
The Growing Importance of a Tech Savvy Astronomy and Astrophysics Workforce
Dara Norman, Kelle Cruz, Vandana Desai +26
Fundamental coding and software development skills are increasingly necessary for success in nearly every aspect of astronomical and astrophysical research as large surveys and hig…
A Dwarf Disrupting -- Andromeda XXVII and the North West Stream
Janet Preston, Michelle L. M. Collins, Rodrigo A. Ibata +10
We present a kinematic and spectroscopic analysis of 38 red giant branch stars, in 7 fields, spanning the dwarf spheroidal galaxy Andromeda XXVII and the upper segment of the North…
