Spectroscopic analysis of DA white dwarfs from the McCook & Sion catalog
A. Gianninas, P. Bergeron, M. T. Ruiz
For some years now, we have been gathering optical spectra of DA white dwarfs in an effort to study and define the empirical ZZ Ceti instability strip. However, we have recently ex…
Broad-line region size and black hole mass in high-z AGN
Ismael Botti, Paulina Lira, Hagai Netzer +3
In this contribution we briefly review the reverberation mapping technique and its results for low and intermidiate luminosity AGNs. Then we present a monitoring campaign of high-l…
Time Dilation in Type Ia Supernova Spectra at High Redshift
S. Blondin, T. M. Davis, K. Krisciunas +29
We present multiepoch spectra of 13 high-redshift Type Ia supernovae (SNe Ia) drawn from the literature, the ESSENCE and SNLS projects, and our own separate dedicated program on th…
12CO(3-2) Emission in Spiral Galaxies: Warm Molecular Gas in Action?
Gaspar Galaz, Paulo Cortes, Leonardo Bronfman +1
Using the APEX sub-millimeter telescope we have investigated the 12CO(3-2) emission in five face-on nearby barred spiral galaxies, where three of them are high surface brightness g…
Observations of the Naked-Eye GRB 080319B: Implications of Nature's Brightest Explosion
J. S. Bloom, D. A. Perley, W. Li +18
The first gamma-ray burst (GRB) confirmed to be bright enough to be seen with the naked eye, GRB 080319B at redshift z = 0.937, allowed for exquisite follow-up observations across…
The vertical velocity dispersion profile of the Galactic thick disk
C. Moni Bidin, T. M. Girard, G. Carraro +4
We present the results of radial velocity measurements of 770 thick disk red giants toward the South Galactic Pole, vertically distributed from 0.5 kpc to 5 kpc with respect to the…
