Leo P: How Many Metals can a Very Low-Mass, Isolated Galaxy Retain?
Kristen B. W. McQuinn, Evan D. Skillman, Andrew Dolphin +7
Leo P is a gas-rich dwarf galaxy with an extremely low gas-phase oxygen abundance (3% solar). The isolated nature of Leo P enables a quantitative measurement of metals lost solely…
Extragalactic HI Surveys
Riccardo Giovanelli, Martha P. Haynes
We review the results of HI line surveys of extragalactic sources in the local Universe. In the last two decades major efforts have been made in establishing on firm statistical gr…
When is Stacking Confusing?: The Impact of Confusion on Stacking in Deep HI Galaxy Surveys
Michael G. Jones, Martha P. Haynes, Riccardo Giovanelli +1
We present an analytic model to predict the HI mass contributed by confused sources to a stacked spectrum in a generic HI survey. Based on the ALFALFA correlation function, this mo…
CARMA CO Observations of Three Extremely Metal-Poor, Star-Forming Galaxies
Steven R. Warren, Edward Molter, John M. Cannon +11
We present sensitive CO (J = 1 - 0) emission line observations of three metal-poor dwarf irregular galaxies Leo P (Z ~ 3% Z_Solar), Sextans A (Z ~ 7.5% Z_Solar), and Sextans B (Z ~…
Environmental dependence of the HI mass function in the ALFALFA 70% catalogue
Michael G. Jones, Emmanouil Papastergis, Martha P. Haynes +1
We search for environmental dependence of the HI mass function in the ALFALFA 70% catalogue. The catalogue is split into quartiles of environment density based on the projected nei…
The Optical Luminosity Function of Void Galaxies in the SDSS and ALFALFA Surveys
Crystal M. Moorman, Michael S. Vogeley, Fiona Hoyle +3
We measure the r-band galaxy luminosity function (LF) across environments over the redshift range 0<<0.107 using the SDSS. We divide our sample into galaxies residing in large s…
Searching for Optical Counterparts to Ultra-compact High Velocity Clouds: Possible Detection of a Counterpart to AGC 198606
William Janesh, Katherine L. Rhode, John J. Salzer +6
We report on initial results from a campaign to obtain optical imaging of a sample of Ultra Compact High Velocity Clouds (UCHVCs) discovered by the ALFALFA neutral hydrogen (HI) su…
The Effect of Structure and Star Formation on the Gas Content of Nearby Galaxies
Toby Brown, Barbara Catinella, Luca Cortese +3
We revisit the main HI-to-stellar mass ratio (gas fraction) scaling relations, taking advantage of the HI spectral stacking technique to understand the dependence of gas content on…
The role of bars in quenching star formation from z = 3 to the present epoch. Halpha3: an Halpha imaging survey of HI selected galaxies from ALFALFA, VI
G. Gavazzi, G. Consolandi, M. Dotti +10
A growing body of evidence indicates that the star formation rate per unit stellar mass (sSFR) decreases with increasing mass in normal "main-sequence" star forming galaxies. Many…
Leo P: An Unquenched Very Low-Mass Galaxy
Kristen B. W. McQuinn, Evan D. Skillman, Andrew Dolphin +8
Leo P is a low-luminosity dwarf galaxy discovered through the blind HI Arecibo Legacy Fast ALFA (ALFALFA) survey. The HI and follow-up optical observations have shown that Leo P is…
Halpha3: an Halpha imaging survey of HI selected galaxies from ALFALFA. V: The Coma Supercluster survey completion
Giuseppe Gavazzi, Guido Consolandi, Elisa Viscardi +8
Neutral hydrogen represents the major observable baryonic constituent of galaxies that fuels the formation of stars through the transformation in molecular hydrogen. The emission o…
Spectroscopic Confusion: Its Impact on Current and Future Extragalactic HI Surveys
Michael G. Jones, Emmanouil Papastergis, Martha P. Haynes +1
We present a comprehensive model to predict the rate of spectroscopic confusion in HI surveys, and demonstrate good agreement with the observable confusion in existing surveys. Gen…
(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,…
Characterizing the Star Formation of the Low-Mass SHIELD Galaxies from Hubble Space Telescope Imaging
Kristen. B. W. McQuinn, John M. Cannon, Andrew E. Dolphin +8
The Survey of HI in Extremely Low-mass Dwarfs (SHIELD) is an on-going multi-wavelength program to characterize the gas, star formation, and evolution in gas-rich, very low-mass gal…
