Early-type galaxies with neutral hydrogen in the Virgo cluster from the ALFALFA survey
S. di Serego Alighieri, M. Grossi, C. Giovanardi +2
We extend our published work on the neutral hydrogen content of early-type galaxies in the Virgo cluster using the catalogue of detected sources from the ALFALFA survey, by showing…
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…
Passively Evolving Early-type Galaxies at 1.4<z<2.5 in the Hubble Ultra Deep Field
E. Daddi, A. Renzini, N. Pirzkal +13
We report on a complete sample of 7 luminous early-type galaxies in the Hubble Ultra Deep Field (UDF) with spectroscopic redshifts between 1.39 and 2.47 and to K<23 AB. Using the B…
An overdensity of galaxies at z=5.9 +/-0.2 in the Ultra Deep Field confirmed using the ACS grism
S. Malhotra, J. E. Rhoads, N. Pirzkal +17
We present grism spectra taken with the Advanced Camera for Surveys to identify 29 red sources with (i'-z') > 0.9 in the Hubble Ultra Deep Field (HUDF). Of these 23 are found to be…
Metal enrichment in near-IR luminous galaxies at z~2: signatures of proto-ellipticals?
Duilia de Mello, E. Daddi, A. Renzini +4
We present the analysis of the coadded rest-frame UV spectrum (1200<z<2000 A) of five K-luminous galaxies at z~2 from the K20 survey. The composite spectrum is characterized by str…
