The Absence of Diffuse Gas around the Dwarf Spheroidal Galaxy Leo I
(1997)
We have obtained spectra of three QSO/AGNs with the GHRS aboard the Hubble Space Telescope to search for absorption from low column density gas in the halo of the dwarf spheroidal (dSph) galaxy Leo I. The probe sight lines ...
Gas segregation in the interacting system Arp 105
(1997)
Arp 105 is an example of a collision between an infrared luminous spiral (NGC 3561A) and an elliptical (NGC 3561B) galaxy in a cluster of galaxies. Duc & Mirabel (1994) reported in this system the genesis of star{forming ...
Starbursts in H II Galaxies
(1997)
H II galaxies fall at the lower end on the scale of the energy output of their starbursts. Still, they are genuine Starburst Galaxies, producing large numbers of massive stars, and at a rate which is unsustainable in the ...
H 2O and OH Masers as Probes of the Obscuring Torus in NGC 1068
(1996)
We report the discovery of OH masers and positionally resolved H_2_O maser emission in the nucleus of NGC 1068. The brightest H_2_O masers are associated with the radio continuum component that is probably the location of ...

A Survey of Low Surface Brightness Dwarf Galaxies to Detect H i-rich Companions
(1996)
We have conducted a survey for H I-rich companions in the vicinity of low surface brightness (LSB) dwarf galaxies, objects that are characterized by low rates of massive star formation. This survey complements our earlier ...
High-Velocity H I in the Spiral Galaxy NGC 5668
(1996)
The nature and origin of the high-velocity clouds (HVCs) of neutral hydrogen in our Galaxy are not well understood, in part because of the uncertain distances to the clouds. As a result it is difficult to measure the mass ...
