Formation of Double Compact Objects
V. Kalogera, K. Belczynski, C. Kim +2
Current observations of double neutron stars provide us with a wealth of information that we can use to investigate their evolutionary history and the physical conditions of neutro…
Constraining population synthesis models via empirical binary compact object merger and supernovae rates
R. O'Shaughnessy, C. Kim, V. Kalogera +1
The observed samples of supernovae (SN) and double compact objects (DCOs) provide several critical constraints on population-synthesis models: the parameters of these models must b…
Mapping population synthesis event rates on model parameters II: Convergence and accuracy of multidimensional fits
R. O'Shaughnessy, V. Kalogera, K. Belczynski
Binary population synthesis calculations and associated predictions, especially event rates, are known to depend on a significant number of input model parameters with different de…
Coherent searches for periodic gravitational waves from unknown isolated sources and Scorpius X-1: results from the second LIGO science run
The LIGO Scientific Collaboration
We carry out two searches for periodic gravitational waves using the most sensitive few hours of data from the second LIGO science run. The first search is targeted at isolated, pr…
Probing the Low-Luminosity XLF in Normal Elliptical Galaxies
D. -W. Kim, G. Fabbiano, V. Kalogera +8
We present the first low luminosity (LX > 5 - 10 1036 erg s-1) X-ray luminosity functions (XLFs) of low-mass X-ray binaries (LMXBs) determined for two typical old elliptical galaxi…
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…
