A 610-MHz Galactic Plane Pulsar Search with the Giant Meterwave Radio Telescope
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 timing parameters, obtained in follow up observations with the Lovell Telescope at Jodrell Bank Observatory and the GMRT, are presented.
متن کاملDiscovery of the Radio and X-ray Counterpart of Tev Γ-ray Source Hess J1731-347
We discover a faint shell-type radio and X-ray source, G353.6-0.7, associated with HESS J1731-347. G353.6-0.7 is likely an old supernova remnant (SNR), based on radio (0.8 GHz, 1.4 GHz and 5 GHz), infrared (8 µm from the GLIMPSE Legacy Project and 21 µm from the Midcourse Space Experiment), and X-ray (0.1 keV-2.4 keV from the ROSAT survey and 5-20 keV from the INTEGRAL survey) data. The SNR, ce...
متن کاملRadio counterparts to extreme X-ray YSO’s
We search for radio counterparts to two recentlydetected strong X-ray sources associated with highly embedded young stellar objects (SVS4/EC 95 and SVS16). We detect a radio source (S68-2) consistent with the position of EC95. We fail to detect a counterpart for SVS16, and place upper limits on its quiescent radio brightness. For S68-2, we show that the radio source has a falling spectrum, sugg...
متن کاملDiscovery 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 کاملRadio Propagation Modeling on 433 MHz
In wireless network design and positioning it is essential to use radio propagation models for the applied frequency and environment. There are many propagation models available for both indoor and outdoor environments; however, they are not applicable for 433 MHz ISM frequency, which is perfectly suitable for smart metering and sensor networking applications. During our work, we gathered the m...
