Detection of an Optical Counterpart to the ALFALFA Ultra-compact High Velocity Cloud AGC 249525
William Janesh, Katherine L. Rhode, John J. Salzer +5
We report on the detection at 98% confidence of an optical counterpart to AGC 249525, an Ultra-Compact High Velocity Cloud (UCHVC) discovered by the ALFALFA blind neutral hydrog…
ALFALFA Discovery of the Most Metal-Poor Gas-Rich Galaxy Known: AGC 198691
Alec S. Hirschauer, John J. Salzer, Evan D. Skillman +12
We present spectroscopic observations of the nearby dwarf galaxy AGC 198691. This object is part of the Survey of HI in Extremely Low-Mass Dwarfs (SHIELD) project, which is a multi…
(Almost) Dark HI Sources in the ALFALFA Survey: The Intriguing Case of HI1232+20
Steven Janowiecki, Lukas Leisman, Gyula Jozsa +7
We report the discovery and follow-up observations of a system of three objects identified by the ALFALFA extragalactic HI survey, cataloged as (almost) dark extragalactic sources,…
A Catalog of Ultra-compact High Velocity Clouds from the ALFALFA Survey: Local Group Galaxy Candidates?
Elizabeth A. K. Adams, Riccardo Giovanelli, Martha P. Haynes
We present a catalog of 59 ultra-compact high velocity clouds (UCHVCs) extracted from the 40% complete ALFALFA HI-line survey. The ALFALFA UCHVCs have median flux densities of 1.34…
