Extreme X-ray Behavior in the Low-Luminosity Active Nucleus of NGC 4395
E. C. Moran, M. Eracleous, K. M. Leighly +4
We present the results of a 17 ks Chandra observation of the nearby dwarf spiral galaxy NGC 4395, focusing on the X-ray properties of the moderate-mass black hole that resides in i…
A Spectroscopic Reconnaissance of UV-Bright Stars
M. Eracleous, R. A. Wade, M. Mateen +1
We have carried out spectroscopic observations and made preliminary classifications of 62 UV-bright stars identified by Lanning on plates taken by A. Sandage. The goal was to searc…
Emission Line Diagnostics of Accretion Flows in Weak-Line Radio Galaxies
Karen T. Lewis, Michael Eracleous, Rita M. Sambruna
In recent surveys of Radio-loud AGN, a new sub-class of objects, known as Weak-Line Radio Galaxies (WLRGs) has emerged. These radio galaxies have only weak, low-ionization optical…
PSR J2229+6114: Discovery of an Energetic Young Pulsar in the Error Box of the EGRET Source 3EG J2227+6122
J. P. Halpern, F. Camilo, E. V. Gotthelf +5
We report the detection of radio and X-ray pulsations at a period of 51.6 ms from the X-ray source RX/AX J2229.0+6114 in the error box of the EGRET source 3EG J2227+6122. An epheme…
