The Arecibo Legacy Fast ALFA Survey: VI. Second HI Source Catalog of the Virgo Cluster Region
Brian R. Kent, Riccardo Giovanelli, Martha P. Haynes +6
We present the third installment of HI sources extracted from the Arecibo Legacy Fast ALFA extragalactic survey. This dataset continues the work of the Virgo ALFALFA catalog. The c…
The Arecibo Legacy Fast ALFA Survey: V. HI Source Catalog of the Anti-Virgo Region at dec=27 degrees
Amelie Saintonge, Riccardo Giovanelli, Martha P. Haynes +5
We present a second catalog of HI sources detected in the Arecibo Legacy Fast ALFA Survey. We report 488 detections over 135 square degrees, within the region of the sky having 22h…
ALFALFA in the Leo Region: Looking for Missing Satellites in HI
Sabrina Stierwalt
The location of two nearby galaxy groups within ~20 Mpc in the Leo region allows for a detailed study of low-mass galaxies. A catalog of HI line detections in Leo (9h36m < RA <11h3…
Optically Unseen HI Detections towards the Virgo Cluster detected in the Arecibo Legacy Fast ALFA Survey
Brian R. Kent, Riccardo Giovanelli, Martha P. Haynes +8
We report the discovery by the Arecibo Legacy Fast ALFA (ALFALFA) survey of eight HI features not coincident with stellar counterparts in the Virgo Cluster region. All of the HI cl…
The Arecibo Legacy Fast ALFA Survey: III. HI Source Catalog of the Northern Virgo Cluster Region
R. Giovanelli, M. P. Haynes, B. R. Kent +20
We present the first installment of HI sources extracted from the Arecibo Legacy Fast ALFA (ALFALFA) extragalactic survey, initiated in 2005. Sources have been extracted from 3-D s…
The Arecibo Legacy Fast ALFA Survey: I. Science Goals, Survey Design and Strategy
Riccardo Giovanelli, Martha P. Haynes, Brian R. Kent
The recently initiated Arecibo Legacy Fast ALFA (ALFALFA) survey aims to map 7000 square degrees of the high galactic latitude sky visible from Arecibo, providing a HI line spectra…
The Arecibo Legacy Fast ALFA Survey: II. Results of Precursor Observations
Riccardo Giovanelli, Martha P. Haynes, Brian R. Kent +17
In preparation for the full Arecibo Legacy Fast ALFA extragalactic HI survey, precursor observations were carried out in Aug--Sep 2004 with the 7-beam Arecibo L-band feed array (AL…
