The Gravitational Torque of Bars
(Astronomical Society of the Pacific, 2002)We have determined the gravitational torque of a sample of 45 galaxies observed at K band with the 4.2m William Herschel Telescope. The results of this sample, combined with those for a sample of 30 galaxies previously ... -
Gravitationally induced inflow in Starbursts and Agn
(2005)There is considerable evidence that the circumnuclear regions of galaxies are intimately related to their host galaxies, most directly through their bars. There is also convincing evidence for relations between the properties ... -
Gravity dependence at the bottom of the main sequence
(1999)We investigate the effects of gravity on the infrared spectra of objects around the M dwarf to brown dwarf transition. We focus on observations of the very low-mass objects TVLM513–46546 and GJ 569B from 1 to 2.5 m. These ... -
Gravity-wave-induced cloud formation in desert dust : Observation with temperature/humidity/aerosol Raman lidar in the framework of earlinet
(ESA PUBLICATIONS DIVISION C/O ESTEC, 2004)The evolution of three cloud layers that formed during the passage of a gravity wave in a desert dust layer was monitored with an advanced Raman lidar. Dust is characterized in terms of particle optical properties. The ... -
GRB 001109: deep JHK upper limits
(2000)We observed the field of GRB 001109 [1] in J, H and Ks with INGRID on the 4.2m William Herschel Telescope on La Palma, Canary Islands on Nov. 9.8 and 11.8 UT, respectively 10 and 59 hours after the burst. The 50" radius ... -
GRB 050814 at z = 5.3 and the Redshift Distribution of Swift GRBs

GRB 080503: Implications of a Naked Short Gamma-Ray Burst Dominated by Extended Emission
(2009)We report on observations of GRB 080503, a short gamma-ray burst (GRB) with very bright extended emission (about 30 times the gamma-ray fluence of the initial spike) in conjunction with a thorough comparison to other short ... -
GRB 081028 and its late-time afterglow re-brightening
(2010)Swift captured for the first time a smoothly rising X-ray re-brightening of clear non-flaring origin after the steep decay in a long gamma-ray burst (GRB): GRB 081028. A rising phase is likely present in all GRBs but is ... -
GRB 090902B: afterglow observations and implications
(2010)The optical-infrared afterglow of the Large Area Telescope (LAT)-detected long-duration burst, GRB 090902B, has been observed by several instruments. The earliest detection by ROTSE-IIIa occurred 80 minutes after detection ... -
GRB 160410a: The first chemical study of the interstellar medium of a short GRB
(2023-03-01)Short gamma-ray bursts (SGRBs) are produced by the coalescence of compact binary systems which are remnants of massive stars. GRB 160410A is classified as a short-duration GRB with extended emission and is currently the ... -
GRB030115 submm upper limit.
(2003)Observations have been made of the infrared afterglow candidate to GRB 030115 (GCN 1818) using the SCUBA bolometer array on the James Clerk Maxwell Telescope located on Mauna Kea, Hawaii. The observations took place on ...
