A new activity phase of the blazar 3C 454.3. Multifrequency observations by the WEBT and XMM-Newton in 2007-2008
C. M. Raiteri, M. Villata, V. M. Larionov +2
We present and analyse the WEBT multifrequency observations of 3C 454.3 in the 2007-2008 observing season, including XMM-Newton observations and near-IR spectroscopic monitoring, a…
Mass functions and photometric binaries in nine open clusters
Saurabh Sharma, A. K. Pandey, K. Ogura +4
Using homogeneous CCD photometric data from the 105-cm Kiso Schmidt telescope covering a 50' x 50' field, we study the mass functions (MFs) of nine open clusters. The ages and Gala…
The dark nature of GRB 051022 and its host galaxy
A. J. Castro-Tirado, M. Bremer, S. McBreen +17
We present multiwavelength (X-ray/optical/near-infrared/millimetre) observations of GRB 051022 between 2.5 hours and ~1.15 yr after the event. It is the most intense gamma-ray burs…
Wide Field CCD photometry around nine open clusters
S. Sharma, A. K. Pandey, K. Ogura +3
In this paper we study the evolution of core and corona of nine open clusters using the projected radial density profiles derived from homogeneous CCD photometric data obtained thr…
Optical and X-ray studies of chromospherically active stars : FR Cancri, HD 95559 and LO Pegasi
J. C. Pandey, K. P. Singh, S. A. Drake +1
We present a multiwavelength study of three chromospherically active stars, namely FR Cnc (= BD +16\degr 1753), HD 95559 and LO Peg (=BD +22\degr 4409), including newly obtained op…
A comprehensive CCD photometric study of the open cluster NGC 2421
R. K. S. Yadav, Ram Sagar
We present the CCD photometry in the region of the open cluster NGC 2421. Radius of the cluster is determined as 3.0 using stellar density profile. Our Stud…
