Discovery of a Supernova Explosion at Half the Age of the Universe and its Cosmological Implications
S. Perlmutter, G. Aldering, M. Della Valle +20
The ultimate fate of the universe, infinite expansion or a big crunch, can be determined by measuring the redshifts, apparent brightnesses, and intrinsic luminosities of very dista…
A BeppoSAX LECS observation of the super-soft source CAL83
A. N. Parmar, P. Kahabka, H. W. Hartmann +1
We report on a BeppoSAX Low-Energy Concentrator Spectrometer (LECS) observation of the super-soft source (SSS) CAL83. The X-ray emission in SSS is believed to arise from nuclear bu…
Stellar Populations in Three Outer Fields of the LMC
Marla C. Geha, Jon A. Holtzman, Jeremy R. Mould +16
We present HST photometry for three fields in the outer disk of the LMC extending approximately four magnitudes below the faintest main sequence turnoff. We cannot detect any stron…
WFPC2 Observations of NGC 454: an Interacting Pair of Galaxies
M. Stiavelli, N. Panagia, C. M. Carollo +3
We present WFPC2 images in the F450W, F606W and F814W filters of the interacting pair of galaxies NGC 454. Our data indicate that the system is in the early stages of interaction.…
Radial Velocities of Globular Clusters in the Giant Elliptical Galaxy NGC 1399
Dante Minniti, Markus Kissler-Patig, Paul Goudfrooij +1
We report on the radial velocity measurements of 18 globular clusters and one dE galaxy in the field of the giant elliptical galaxy NGC 1399, the dominant galaxy of the Fornax clus…
A BeppoSAX observation of the X-ray pulsar 1E 2259+586 and the supernova remnant G109.1-1.0 (CTB 109)
A. N. Parmar, T. Oosterbroek, F. Favata +4
The 7 s X-ray pulsar 1E2259+586 and the supernova remnant (SNR) G109.1-1.0 (CTB 109) were observed by BeppoSAX in 1996 November. The pulse period of 6.978914 +/- 0.000006 s implies…
