ALFALFA HI Content and Star Formation in Virgo Cluster Early-Type Dwarfs
R. A. Koopmann, R. Giovanelli, M. P. Haynes +1
The ALFALFA (Arecibo Legacy Fast ALFA) blind survey is providing a census of HI in galaxies of all types in a range of environments. Here we report on ALFALFA results for Virgo Clu…
A 500 kpc HI Extension of the Virgo Pair NGC4532/DDO137 Detected by the Arecibo Legacy Fast ALFA (ALFALFA) Survey
R. A. Koopmann, R. Giovanelli, M. P. Haynes +6
We report the discovery of a ~500 kpc HI extension southwest of the Virgo Cluster HI-rich pair NGC 4532/DDO 137, detected as part of the Arecibo Legacy Fast ALFA (ALFALFA) Survey.…
The HI content of Early-Type Galaxies from the ALFALFA survey I. Catalogued HI sources in the Virgo cluster
S. di Serego Alighieri, G. Gavazzi, C. Giovanardi +8
Aims: We are using the Arecibo Legacy Fast ALFA survey (ALFALFA), which is covering 17% of the sky at 21 cm, to study the HI content of Early-Type galaxies (ETG) in an unbiased way…
Virgo Early-Type Dwarfs in ALFALFA
Rebecca A. Koopmann
Early-type dwarf galaxies dominate cluster populations, but their formation and evolutionary histories are poorly understood. The ALFALFA (Arecibo Legacy Fast ALFA) survey has comp…
