A search for HI in five elliptical galaxies with fine structure

Autor: Hibbard, JE, Sansom, Anne E

We report on VLA H I spectral line observations of five early-type galaxies classified as optically peculiar because of the presence of jets, ripples, or other optical fine structure. We detect H I within the primary beam (30' half-power beamwidth) i

The re-ionization of the intergalactic medium that takes place at redshift greater than 5, when the first stars or active galactic nuclei ignite, may create a distinctive spatial and spectral signature in the radio background. Detection of a global s

We have mapped 1.3 degree(2) of the Coma cluster from the core to beyond the NGC4839 group. Here, we present radial U-band Coma galaxy luminosity functions (LF). The central LF can be represented by a Schechter function, but the radial LFs have very

An Hi and H alpha atlas of ring galaxies: Probing the neutral interstellar medium/starburst connection

We have combined Halpha and HI images of eight ring galaxies to investigate the factors regulating starburst activity on large scales. Starburst activity is strongly correlated with the attainment of very high Hi surface densities (Sigma(HI)) in the

Constraints on high-velocity cloud analogs in external groups and galaxies

Autor: Zwaan, M, Hibbard, JE, Rupen, MP, VanGorkom, JH

The hypothesis that high-velocity clouds (HVCs) are Local Group satellites at typical distances of a few hundred kpc to 1.5 Mpc, and with HI masses similar to 10(7) M-circle dot is highly inconsistent with (1) the results from blind Hi surveys, (2) t

Deep HI imaging with the Westerbork Synthesis Radio Telescope in the direction of Abell 2218 has resulted in the first detection of HI 21 cm emission at cosmological distance. The HI signal originates in a galaxy at a projected distance of 1.5 h(100)

H-I 21 cm absorption in Mg (II)-selected systems at moderate redshifts

We present results from a Westerbork Synthesis Radio Telescope (WSRT) survey for HI 21 cm absorption in 62 MgII-selected absorption systems, among which we identify three now HI 21cm absorbers. We use the redshift evolution of the number density of M
