A Timing Signature of Gravitational Radiation from LMXB Neutron Stars

Robert V. Wagoner

The coupled evolution of the spin frequency, core temperature, and r-mode amplitude of an accreting neutron star is calculated. We focus on those conditions that can produce persis…

Analysis of Burst Observations by GLAST's LAT Detector

David L. Band, Seth W. Digel, the GLAST LAT Collaboration +1

Analyzing data from GLAST's Large Area Telescope (LAT) will require sophisticated techniques. The PSF and effective area are functions of both photon energy and the position in the…

Testing the Cosmological Constant as a Candidate for Dark Energy

Jan Kratochvil, Andrei Linde, Eric V. Linder +1

It may be difficult to single out the best model of dark energy on the basis of the existing and planned cosmological observations, because many different models can lead to simila…

Microlensing of gamma ray bursts by stars and MACHOs

Edward A. Baltz, Lam Hui

The microlensing interpretation of the optical afterglow of GRB 000301C seems naively surprising, since a simple estimate of the stellar microlensing rate gives less than one in fo…

Ultraviolet Emission from the Millisecond Pulsar J0437-4715

O. Kargaltsev, G. G. Pavlov, R. W. Romani

We observed PSR J0437-4715 with the FUV-MAMA detector of the Hubble Space Telescope Imaging Spectrometer (STIS) to measure the pulsar's spectrum and pulsations. For the first time,…

Fitting Pulsar Wind Tori

C. -Y. Ng, Roger W. Romani

CXO imaging has shown that equatorial tori, often with polar jets, are very common in young pulsar wind nebulae (PWNe). These structures are interesting both for what they reveal a…
