Pulsar Timing for the Fermi Gamma-ray Space Telescope
D. A. Smith, L. Guillemot, F. Camilo +25
We describe a comprehensive pulsar monitoring campaign for the Large Area Telescope (LAT) on the {\em Fermi Gamma-ray Space Telescope} (formerly GLAST). The detection and study of…
Mapping Hydrogen in the Galaxy, Galactic Halo, and Local Group with ALFA: The GALFA-HI Survey Starting with TOGS
S. J. Gibson, K. A. Douglas, C. Heiles +4
Radio observations of gas in the Milky Way and Local Group are vital for understanding how galaxies function as systems. The unique sensitivity of Arecibo's 305m dish, coupled with…
Super-Massive Neutron Stars
Paulo C. C. Freire
We present here the results of Arecibo timing of PSR B1516+02B, a 7.95-ms pulsar in a binary system with a ~0.17 solar mass companion and an orbital period of 6.85 days located in…
Eight new MSPs in NGC 6440 and NGC 6441
Paulo C. C. Freire, Scott M. Ransom, Steve Begin +4
We report the discovery of five new millisecond pulsars in the globular cluster NGC 6440 and three new ones in NGC 6441; each cluster has one previously known pulsar. Four of the n…
The Eccentric Binary Millisecond Pulsar in NGC 1851
Paulo C. C. Freire, Scott M. Ransom, Yashwant Gupta
PSR J0514-4002A is a 5-ms pulsar is located in the globular cluster NGC 1851; it belongs to a highly eccentric (e = 0.888) binary system. It is one of the earliest known examples o…
Rotational Widths for Use in the Tully-Fisher Relation. II. The Impact of Surface Brightness
Barbara Catinella, Martha P. Haynes, Riccardo Giovanelli
Using a large sample of spiral galaxies for which 21 cm single-dish and/or long-slit optical spectra are available, we make a detailed comparison between various estimates of rotat…
