Abundances and kinematics of a candidate sub-damped Lyman-alpha galaxy toward PHL 1226
L. Christensen, R. E. Schulte-Ladbeck, S. F. Sanchez +5
The spectrum of the quasar PHL 1226 is known to have a strong Mg II and sub-damped Lyman-alpha (sub-DLA) absorption line system with N(HI)=(5+/-2)*10^19 cm^-2 at z=0.1602. Using in…
Skywalking GEMS and UDF
K. Jahnke, S. F. Sanchez, B. Haeussler
The two large colour mosaics of the GEMS and UDF projects, both obtained with the Hubble Space Telescope and ACS, consist of large amounts of data. We present two web application p…
Integral Field Spectroscopy of Extended Lyman-alpha Emission from the DLA Galaxy in Q2233+131
L. Christensen, S. F. Sanchez, K. Jahnke +5
This paper presents observations of an extended Lyman-alpha emission nebula surrounding the galaxy responsible for the Damped Lyman-alpha Absorption (DLA) line in the spectrum of t…
The impact of spanish astrophysics in the 1990's
S. F. Sanchez, C. R. Benn
Spanish astronomy has grown rapidly during the 1990s. The number of papers published per year has doubled, to about 4% of the world total. The number of high-impact papers, however…
Clustering around QSOs at 1<z<1.6
S. F. Sanchez, J. I. Gonzalez-Serrano
Deep and band images (R<24 and B<25) have been obtained of a field of arcmin around seven radio-loud quasars with . A statistically significant e…
