Mid-infrared selection of quasar-2s in Spitzer's First Look Survey
M. Lacy, G. Canalizo, S. Rawlings +6
We present early results from the spectroscopic follow-up of a sample of candidate obscured AGN selected in the mid-infrared from the Spitzer First Look Survey. Our selection allow…
Optical Line profile variability of the B1+neutron star binary system LS I+65 010 = 2S 0114+650
Gloria Koenigsberger, Gabriela Canalizo, Anabel Arrieta +2
We present high resolution spectroscopic observations of the massive X-ray binary system LS I+65 010=2S 0114+650 in the optical wavelength region. A correlation between equivalent…
Low-Ionization BAL QSOs in Ultraluminous Infrared Systems
Gabriela Canalizo, Alan Stockton
Low-ionization broad absorption line (BAL) QSOs present properties that cannot generally be explained by simple orientation effects. We have conducted a deep spectroscopic and imag…
Optical Spectroscopy of the Central Regions of Bright Barred Spiral Galaxies
J. A. Garcia-Barreto, H. Aceves, O. Kuhn +3
Optical red spectra of a set of 18 bright barred spiral galaxies are presented. The study is aimed at determining the local kinematics, and the physical conditions of ionized gas i…
Serendipitous Discovery of a BAL QSO at z = 2.169
Gabriela Canalizo, Alan Stockton, Katherine C. Roth
We report the serendipitous discovery of a BAL QSO at z = 2.169, located 41'' southwest of 3C 48. We present Keck LRIS spectroscopy covering rest frame 1500 A to 2300 A . The C IV…
