An Autograded, Open Educational Resource Assessment Tool for Astronomy Using MyOpenMath
Joshua Tan, Allyson Sheffield, Jana Grcevich
We present an Open Educational Resource system that instructors can use to assign automatically graded, randomized, and scaffolded assessment questions for astronomy classes.
The Gas Content and Stripping of Local Group Dwarf Galaxies
Mary E. Putman, Yong Zheng, Adrian M. Price-Whelan +4
The gas content of the complete compilation of Local Group dwarf galaxies (119 within 2 Mpc) is presented using HI survey data. Within the virial radius of the Milky Way (224 kpc h…
HST Imaging of the Local Volume Dwarf Galaxies Pisces A&B: Prototypes for Local Group Dwarfs
Erik J. Tollerud, Marla C. Geha, Jana Grcevich +3
We present observations of the Pisces A and B galaxies with the Advanced Camera for Surveys on the Hubble Space Telescope. Photometry from these images clearly resolve a Red Giant…
Gas Loss by Ram Pressure Stripping and Internal Feedback From Low Mass Milky Way Satellites
Andrew Emerick, Mordecai-Mark Mac Low, Jana Grcevich +1
The evolution of dwarf satellites of the Milky Way is affected by the combination of ram pressure and tidal stripping, and internal feedback from massive stars. We investigate gas…
Finding gas-rich dwarf galaxies betrayed by their ultraviolet emission
Jennifer Donovan Meyer, J. E. G. Peek, Mary Putman +1
We present ultraviolet (UV) follow-up of a sample of potential dwarf galaxy candidates selected for their neutral hydrogen (HI) properties, taking advantage of the low UV backgroun…
Two Local Volume Dwarf Galaxies Discovered in 21 cm Emission: Pisces A and B
Erik J. Tollerud, Marla C. Geha, Jana Grcevich +2
We report the discovery of two dwarf galaxies, Pisces A and B, from a blind 21 cm HI search. These were the only two galaxies found via optical imaging and spectroscopy of 22 HI cl…
