Absolute Distances to Nearby Type Ia Supernovae via Light Curve Fitting Methods
J. Vinkó, A. Ordasi, T. Szalai +22
We present a comparative study of absolute distances to a sample of very nearby, bright Type Ia supernovae (SNe) derived from high cadence, high signal-to-noise, multi-band photome…
The early phases of the type Iax supernova SN 2011ay
Tamás Szalai, József Vinkó, Krisztián Sárneczky +7
We present a detailed study of the early phases of the peculiar supernova 2011ay based on BVRI photometry obtained at Konkoly Observatory, Hungary, and optical spectra taken with t…
Photometry of Some Recent Gamma-ray Bursts
József Kóbori, János Kelemen, Péter Veres +2
We present the results of the optical, X-ray and gamma-ray analysis of some recent GRBs. The data were obtained by the automated P60 telescope and the Swift telescope (UVOT, XRT an…
Directional Anisotropy of Swift Gamma-Ray Bursts
Péter Veres, Zsolt Bagoly, István Horváth +3
Swift satellite measurements contributed substantially to the gamma-ray burst (GRB) redshift observations through fast slewing to the source of the GRBs. Still, a large number of b…
Analysis of the Swift Gamma-Ray Bursts duration
I. Horvath, L. G. Balazs, Z. Bagoly +3
Two classes of gamma-ray bursts have been identified in the BATSE catalogs characterized by durations shorter and longer than about 2 seconds. There are, however, some indications…
The Collimation and Energetics of the Brightest Swift Gamma-Ray Bursts
S. B. Cenko, D. A. Frail, F. A. Harrison +22
Long-duration gamma-ray bursts (GRBs) are widely believed to be highly-collimated explosions (opening angle theta ~ 1-10 deg). As a result of this beaming factor, the true energy r…
