Luminous Type II supernovae for their low expansion velocities
Ó. Rodríguez, G. Pignata, J. P. Anderson +27
We present optical and near-IR data of three Type II supernovae (SNe II), SN 2008bm, SN 2009aj, and SN 2009au. These SNe display the following common characteristics: signs of earl…
The CHilean Automatic Supernova sEarch (CHASE)
G. Pignata, J. Maza, M. Hamuy +16
The CHASE project started in 2007 with the aim of providing young southern supernovae (SNe) to the Carnegie Supernova Project (CSP) and Millennium Center for Supernova Studies (MCS…
Optical and IR observations of SN 2002dj: some possible common properties of fast expanding SNe Ia
G. Pignata, S. Benetti, P. A. Mazzali +17
As part of the European Supernova Collaboration we obtained extensive photometry and spectroscopy of the type Ia SN 2002dj covering epochs from 11 days before to nearly two years a…
Galaxy Clusters in the Line of Sight to Background Quasars: I. Survey Design and Incidence of MgII Absorbers at Cluster Redshifts
S. Lopez, L. F. Barrientos, P. Lira +7
We describe the first optical survey of absorption systems associated with galaxy clusters at z= 0.3-0.9. We have cross-correlated SDSS DR3 quasars with high-redshift cluster/group…
Tomography of the intergalactic medium with Ly-alpha forests in close QSO pairs
V. D'Odorico, M. Viel, F. Saitta +6
We study the three-dimensional distribution of non virialised matter at z~2 using high resolution spectra of QSO pairs and simulated spectra drawn from cosmological hydrodynamical…
The Physical Nature of Lyman Alpha Emitting Galaxies at z=3.1
Eric Gawiser, Pieter G. van Dokkum, Caryl Gronwall +20
We selected 40 candidate Lyman Alpha Emitting galaxies (LAEs) at z ~=3.1 with observed frame equivalent widths >150A and inferred emission line fluxes >2.5x10^-17 ergs/cm^2/s from…
