Disk dynamics and the X-ray emission of S0 and flat early-type galaxies
Andrea Negri, Silvia Pellegrini, Luca Ciotti
With 2D hydrodynamical simulations, we study the evolution of the hot gas flows in early-type galaxies, focussing on the effects of galaxy rotation on the thermal and dynamical sta…
The effects of flattening and rotation on the temperature of the X-ray halos of elliptical galaxies
Silvia Posacki, Silvia Pellegrini, Luca Ciotti
Elliptical galaxies have hot coronae with X-ray luminosities and mean gas temperatures that span over wide ranges. This variation can be partially due to the energy budget of the h…
Deep Chandra Monitoring Observations of NGC 4278: Catalog of Source Properties
N. J. Brassington, G. Fabbiano, D. -W. Kim +11
We present the properties of the discrete X-ray sources detected in our monitoring program of the globular cluster (GC) rich elliptical galaxy, NGC 4278, observed with Chandra ACIS…
Comparing GC and Field LMXBs in Elliptical Galaxies with deep Chandra and Hubble data
D. -W. Kim, G. Fabbiano, N. J. Brassington +15
(abridged) We present a statistical study of the low-mass X-ray binary (LMXB) populations of three nearby, old elliptical galaxies: NGC 3379, NGC 4278, and NGC 4697. With a cumulat…
Transient Low-Mass X-Ray Binary Populations in Elliptical Galaxies NGC 3379 and NGC 4278
T. Fragos, V. Kalogera, B. Willems +12
We propose a physically motivated and self-consistent prescription for the modeling of transient neutron star (NS) low-mass X-ray binary (LMXB) properties, such as duty cycle (DC),…
