Two Rare Magnetic Cataclysmic Variables with Extreme Cyclotron Features Identified in the Sloan Digital Sky Survey
Paula Szkody, Scott F. Anderson, Gary Schmidt +6
Two newly identified magnetic cataclysmic variables discovered in the Sloan Digital Sky Survey (SDSS), SDSSJ155331.12+551614.5 and SDSSJ132411.57+032050.5, have spectra showing hig…
Age-Dating Ultraluminous Infrared Galaxies Along the Merger Sequence
T. W. Murphy, B. T. Soifer, K. Matthews +1
Imaging spectroscopy using the new Palomar Integral Field Spectrograph is presented for the Pa-alpha line in four ultraluminous infrared galaxies. In most cases, we are able to est…
K band Spectroscopy of Ultraluminous Infrared Galaxies: The 2 Jy Sample
T. W. Murphy, B. T. Soifer, K. Matthews +2
We present near-infrared spectroscopy for a complete sample of 33 ultraluminous infrared galaxies at a resolution of R\approx 1000. Most of the wavelength range from 1.80-2.20 micr…
The Active Nucleus in the Ultraluminous Infrared Galaxy IRAS 08311-2459
T. W. Murphy, B. T. Soifer, K. Matthews +1
Near-infrared spectroscopy using the new Palomar Integral Field Spectrograph indicates the presence of an AGN (active galactic nucleus) in the ultraluminous infrared galaxy IRAS 08…
APM 08279+5255: Keck Near- and Mid-IR High-Resolution Imaging
E. Egami, G. Neugebauer, B. T. Soifer +5
We present Keck high-resolution near-IR (2.2 microns; FWHM~0.15") and mid-IR (12.5 microns; FWHM~0.4") images of APM08279+5255, a z=3.91 IR-luminous BALQSO with a prodigious appare…
Spectroscopy of Infrared Flares from the Microquasar GRS 1915+105
Stephen S. Eikenberry, Keith Matthews, Thomas W. Murphy +4
We present near-infrared medium-resolution () spectra of the microquasar GRS 1915+105 on 1997 August 13-15 UTC from the Hale 200-inch telescope. The spectra showed broa…
