A multiphysics and multiscale software environment for modeling astrophysical systems
Simon Portegies Zwart, Steve McMillan, Stefan Harfst +2
We present MUSE, a software framework for combining existing computational tools for different astrophysical domains into a single multiphysics, multiscale application. MUSE facili…
Models for Low-Mass X-Ray Binaries in the Elliptical Galaxies NGC3379 and NGC4278: Comparison with Observations
T. Fragos, V. Kalogera, K. Belczynski +11
We present theoretical models for the formation and evolution of populations of low-mass X-ray binaries (LMXB) in the two elliptical galaxies NGC 3379 and NGC 4278. The models are…
Deep Chandra Monitoring Observations of NGC 3379: 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 `typical' elliptical galaxy, NGC 3379, observed with Chandra ACIS-S in five separa…
Black Hole Formation in X-Ray Binaries: The Case of XTE J1118+480
T. Fragos, B. Willems, N. Ivanova +1
In recent years, an increasing number of proper motions have been measured for Galactic X-ray binaries. When supplemented with accurate determinations of the component masses, orbi…
The Eclipsing ULX in NGC 3379
G. Fabbiano, D. -W. Kim, T. Fragos +9
We report recent Chandra observations of the ULX in the elliptical galaxy NGC3379 that clearly detect two flux variability cycles. Comparing these data with the Chandra observation…
On the Formation and Progenitor of PSR J0737-3039: New Constraints on the Supernova Explosion Forming Pulsar B
B. Willems, J. Kaplan, T. Fragos +2
We revisit the formation of PSR J0737-3039, taking into account the most recent observational constraints. We show that the most likely kick velocity and progenitor parameters depe…
