▪ Abstract Blueshifted absorption lines in the UV and X-ray spectra of active galaxies reveal
the presence of massive outflows of ionized gas from their nuclei. The “intrinsic” UV and X …

We present the photometric calibration of the Advanced Camera for Surveys (ACS). The
ACS was installed in the Hubble Space Telescope (HST) in 2002 March. It comprises three …

We present a comprehensive study to measure the locations of gamma-ray bursts (GRBs)
relative to their host galaxies. In total, we find the offsets of 20 long-duration GRBs from their …

We present a nearly complete rapid neutron-capture process (r-process) chemical inventory
of the metal-poor ([Fe/H]=− 1.46±0.10) r-process-enhanced ([Eu/Fe]=+ 1.32±0.08) halo star …

The B emission-line stars are rapid rotators that were probably spun up by mass and
angular momentum accretion through mass transfer in an interacting binary. Mass transfer …

ABSTRACT The Space Telescope Imaging Spectrograph (STIS) instrument was installed on
the Hubble Space Telescope (HST) during the second servicing mission, in 1997 February …

We present a study of metal-enriched halo gas traced by Mg ii and C iv absorption at z< 2 in
the MUSE Analysis of Gas around Galaxies survey and the Quasar Sightline and Galaxy …

Using high-resolution ultraviolet spectra of 16 low-z QSOs obtained with the E140M echelle
mode of the Space Telescope Imaging Spectrograph, we study the physical conditions and …

We present new coronagraphic images of β Pictoris obtained with the Space Telescope
Imaging Spectrograph (STIS) in 1997 September. The high-resolution images (0 &farcs; 1) …

We detect Lyα absorption from the escaping atmosphere of HD 63433c, a R= 2.67R⊕, P=
20.5 day mini-Neptune orbiting a young (440 Myr) solar analog in the Ursa Major Moving …
