Measurements of Variability of Low Mass X-ray Binary Candidates in the Early-Type Galaxy NGC 4697 from Multi-Epoch Chandra X-ray Observations
Gregory R. Sivakoff, Andrés Jord'an, Adrienne M. Juett +2
Multi-epoch Chandra X-ray observations of nearby massive early-type galaxies open up the study of an important regime of low-mass X-ray binary (LMXB) behavior -- long term variabil…
Deep Chandra X-ray Observations of Low Mass X-ray Binary Candidates in the Early-Type Galaxy NGC 4697
Gregory R. Sivakoff, Andrés Jordán, Adrienne M. Juett +2
Chandra X-ray observations routinely resolve tens to hundreds of low-mass X-ray binaries (LMXBs) per galaxy in nearby massive early-type galaxies. These studies have raised importa…
Evidence for Non-Hydrostatic Gas Motions in the Hot ISM of Centaurus A
R. P. Kraft, M. J. Hardcastle, G. R. Sivakoff +16
We present preliminary results from a deep (600 ks) {\em Chandra} observation of the hot interstellar medium of the nearby early-type galaxy Centaurus A (Cen A). We find a surface…
Variable Low-Mass X-ray Binaries in Early-Type Galaxies
Gregory R. Sivakoff, Andrés Jordán, Adrienne M. Juett +2
As the Chandra X-ray Observatory mission matures, increasing numbers of nearby galaxies are being observed multiple times, sampling the variability of extragalactic X-ray binaries…
Normal Globular Cluster Systems in Massive Low Surface Brightness Galaxies
Daniela Villegas, Markus Kissler-Patig, Andrés Jordán +2
We present the results of a study of the globular cluster systems of 6 massive spiral galaxies, originally cataloged as low surface brightness galaxies but here shown to span a wid…
FIRST `Winged' and `X'-shaped Radio Source Candidates
C. C. Cheung
A small number of double-lobed radio galaxies (17 from our own census of the literature) show an additional pair of low surface brightness `wings', thus forming an overall `X'-shap…
