Discovery of three new pulsars in a 610 MHz pulsar survey with the GMRT
We report on the discovery of three new pulsars in the first blind survey of the north Galactic plane (45◦ < l < 135◦; |b| < 1◦) with the Giant Meterwave Radio telescope (GMRT) at an intermediate frequency of 610 MHz. The survey covered 106 square degrees with a sensitivity of roughly 1 mJy to long-period pulsars (pulsars with period longer than 1 s). The three new pulsars have periods of 318, ...
متن کاملInfrared Observations of Galaxy Clusters
However evidence is growing for the presence of well evolved rich clusters and cluster galaxies at high redshift (above z=0.5-1; Dickinson 1997, Mushotzky and Loewenstein 1997), which sets a key constraint on galaxy evolution models and on structure formation models as well. After IRAS, which proved that starbursts emitted mostly in the infrared (Sanders & Mirabel 1996), ISOCAM is finding a str...
متن کاملSpitzer Observations of Galaxy Clusters
We present preliminary results of a project to study three rich nearby clusters of galaxies with the Spitzer space telescope. The Spitzer observations in the four IRAC and three MIPS bands cover a region up to three virial radii, approximately, and have been recently completed. On the basis of the first Spitzer images, we followed up spectroscopically the far-infrared sources with the multi-fib...
متن کاملGMRT Radio Halo Survey in galaxy clusters at z = 0 . 2 – 0 . 4 . I . The REFLEX sub – sample
Aims. We present the first results of an ongoing project devoted to the search of giant radio halos in galaxy clusters located in the redshift range z=0.2–0.4. One of the main goals of our study is to measure the fraction of massive galaxy clusters in this redshift interval hosting a radio halo, and to constrain the expectations of the particle re–acceleration model for the origin of non–therma...
متن کامل3c 129 : the Gmrt Observations
We present radio maps of the head-tail radio galaxy, 3C 129 at 240 and 610 MHz using the Giant Metrewave Radio Telescope. We have studied in detail the morphology of the source and the distribution of spectral index over the object. We find large-scale spectral steepening along the jet away from the core. Using synchrotron spectral ageing theory, we infer the age (time since particle accelerati...
