AGN activity and the misaligned hot ISM in the compact radio elliptical NGC4278
(2012-10-20)
The analysis of a deep (579ks) Chandra ACIS pointing of the elliptical galaxy NGC4278, which hosts a low-luminosity active galactic nucleus (AGN) and compact radio emission, allowed us to detect extended emission from hot ...
The Spectral and Temporal Properties of Transient Sources in Early-type Galaxies
(2012-08-20)
We report the spectral and temporal variability properties of 18 candidate transient (TC) and potential transient (PTC) sources detected in deep multi-epoch Chandra observation of the nearby elliptical galaxies, NGC3379, ...
Probing the X-ray binary populations of the ring galaxy NGC 1291
(2012-04)
We present Chandra studies of the X-ray binary (XRB) populations in the bulge and ring regions of the ring galaxy NGC 1291. We detect 169 X-ray point sources in the galaxy, 75 in the bulge and 71 in the ring, utilizing the ...
