Faint galaxies around quasars at z=1 and gravitational lensing of distant objects
J. W. Fried
Very deep imaging data of three optically luminous radio-loud quasars with redshifts between z=0.9 and z=1.36 are presented. The data are complete for galaxies down to R=26. There…
Are the Perseus-Pisces chain and the Pavo-Indus wall connected?
Helene Di Nella, W. Couch, G. Paturel +1
A significant empty region was found between the southern Pavo- Indus (PI) wall and the northern Perseus-Pisces (PP) chain. This survey tests the reality of this void which may sim…
The OMC-1 molecular hydrogen outflow as a fragmented stellar wind bubble
Mark J. McCaughrean, Mordecai-Mark Mac Low
We present new images of the OMC-1 molecular hydrogen outflow, made using long-slit spectroscopy in order to accurately subtract the underlying continuum emission. These images rev…
Do dwarf spheroidal galaxies contain dark matter?
A. Burkert
The amount of dark matter in the four galactic dwarf spheroidals with large mass-to-light ratios is investigated. Sextans has a cut-off radius which is equal to the expected tidal…
An Interstellar Conduction Front Within a Wolf-Rayet Ring Nebula Observed with the GHRS
Bram Boroson, Richard McCray, Christina Oelfke Clark +4
With the High Resolution Spectrograph aboard the Hubble Space Telescope we obtained high signal-to-noise (S/N > 200 - 600 per 17 km/s resolution element) spectra of narrow absorpti…
Substructure in the Globular Cluster System of the Milky Way
A. Burkert, G. Smith
The kinematical and spatial properties of the metal-rich globular clusters in the Galaxy ([Fe/H] > -0.8) indicates that these objects do not comprise a homogeneous population. Thre…
A Narrowband Imaging Survey for High Redshift Galaxies in the Near Infrared
D. Thompson, F. Mannucci, S. V. W. Beckwith
A narrowband imaging survey of 276 square minutes of arc was carried out at near infrared wavelengths to search for emission line objects at high redshifts. Most of the fields cont…
Consequences of a Non-Detection of Forming Galaxies by an Infrared Survey
F. Mannucci, D. Thompson, S. V. W. Beckwith
We present the results of a narrowband search for forming galaxies at high redshifts. Given the coverage of 276 square minutes of arc, this is the most extended search for extragal…
The Redshift Evolution of the Stellar Populations in Elliptical Galaxies
Ralf Bender, Bodo Ziegler, Gustavo Bruzual
Velocity dispersions and Mg absorption line-strengths Mg have been measured for a sample of 16 ellipticals in 3 clusters at a redshift of 0.37. Like local cluster elliptica…
An IR Study of the Velocity Structure of the Cometary Compact HII region G29.96-0.02
Stuart Lumsden, Melvin Hoare
We have mapped the velocity structure of the cometary compact HII region G29.96-0.02 using long-slit echelle spectra of the HI Br gamma line. This technique detects line emission o…
Dormant dwarf spheroidal galaxies, deactivated by Type Ia supernovae
A. Burkert, P. Ruiz-Lapuente
Some dwarf spheroidal galaxies have experienced many Gyrs long periods without star formation. We show that Type Ia supernovae, formed from a first generation of stars, can delay a…
