MAGIC upper limits on the very high energy emission from GRBs
J. Albert, E. Aliu, H. Anderhub +57
The fast repositioning system of the MAGIC Telescope has allowed during its first data cycle, between 2005 and the beginning of year 2006, observing nine different GRBs as possible…
How robust are inflation model and dark matter constraints from cosmological data?
Jan Hamann, Steen Hannestad, Martin S. Sloth +1
High-precision data from observation of the cosmic microwave background and the large scale structure of the universe provide very tight constraints on the effective parameters tha…
Break in the VHE spectrum of PG 1553+113: new upper limit on its redshift?
D. Mazin, F. Goebel
PG 1553+113 is a known BL Lac object, newly detected in the GeV-TeV energy range by H.E.S.S and MAGIC. The redshift of this source is unknown and a lower limit of was re…
First bounds on the very high energy gamma-ray emission from Arp 220
J. Albert et al.
Using the Major Atmospheric Gamma Imaging Cherenkov Telescope (MAGIC), we have observed the nearest ultra-luminous infrared galaxy Arp 220 for about 15 hours. No significant signal…
Observations of AGNs using PACT
D. Bose, V. R. Chitnis, P. R. Vishwanath +5
We report our observations on 4 AGNs viz, Mkn421, Mkn501, 1ES1426+428 and ON231 belonging to a sub-class called blazars. The observations were carried out using the Pachmarhi Array…
Probing the internal solar magnetic field through g-modes
T. I. Rashba, V. B. Semikoz, S. Turck-Chieze +1
The observation of g-mode candidates by the SoHO mission opens the possibility of probing the internal structure of the solar radiative zone (RZ) and the solar core more directly t…
