The Swift gamma-ray burst mission
TLDR
The Swift mission will determine the origin of GRB, classify GRBs and search for new types, study the interaction of the ultrarelativistic outflows of GRBs with their surrounding medium, and use GRBs to study the early universe out to z >10. Expand
Measurements of $\Omega$ and $\Lambda$ from 42 high redshift supernovae
We report measurements of the mass density, Omega_M, and cosmological-constant energy density, Omega_Lambda, of the universe based on the analysis of 42 Type Ia supernovae discovered by the SupernovaExpand
The Hubble Diagram to Redshift >6 from 69 Gamma-Ray Bursts
One of the few ways to measure the properties of dark energy is to extend the Hubble diagram (HD) to higher redshifts with gamma-ray bursts (GRBs). GRBs have at least five properties (their spectralExpand
COMPREHENSIVE PHOTOMETRIC HISTORIES OF ALL KNOWN GALACTIC RECURRENT NOVAE
I collect virtually all photometry of the 10 known galactic recurrent novae (RNe) and their 37 known eruptions. This consists of my modern measures of nearly all archival plates (providing the onlyExpand
Discovery of a supernova explosion at half the age of the Universe
The ultimate fate of the Universe, infinite expansion or a big crunch, can be determined by using the redshifts and distances of very distant supernovae to monitor changes in the expansion rate. WeExpand
An absence of ex-companion stars in the type Ia supernova remnant SNR 0509−67.5
TLDR
The central region of the supernova remnant SNR 0509−67.5 in the Large Magellanic Cloud contains no ex-companion star to a visual magnitude limit of 26.9 (an absolute magnitude of MV = +8.4) within a region of radius 1.43 arcseconds, which rules out all published single-degenerate models for this supernova.

New Constraints on ΩM, ΩΛ, and w from an Independent Set of 11 High-Redshift Supernovae Observed with the Hubble Space Telescope*
We report measurements ofM, � � , and w from 11 supernovae (SNe) at z ¼ 0:36 0:86 with high-quality light curves measured using WFPC2 on the Hubble Space Telescope (HST). This is an independent setExpand
A Problem with the Clustering of Recent Measures of the Distance to the Large Magellanic Cloud
The distance to the Large Magellanic Cloud (LMC) has long been of key importance for the distance ladder and the distances to all galaxies, and as such many groups have provided measurements of itsExpand
Optical and Radio Observations of the Afterglow from GRB 990510: Evidence for a Jet
We present multicolor optical and two-frequency radio observations of the bright BeppoSAX event GRB 990510. Neither the well-sampled optical decay nor the radio observations are consistent withExpand
CATALOG OF 93 NOVA LIGHT CURVES: CLASSIFICATION AND PROPERTIES
We present a catalog of 93 very-well-observed nova light curves. The light curves were constructed from 229,796 individual measured magnitudes, with the median coverage extending to 8.0 mag belowExpand
