Electromagnetic follow-up of gravitational wave transient signal candidates
Electromagnetic follow-up gravitational wave transient signal candidates
2012/2/24
Pioneering efforts aiming at the development of multi-messenger gravitational wave and electromagnetic astronomy have been made. An electromagnetic observation follow-up program of candidate gravitati...
Applications of muon signal to electromagnetic signal showers universality for mass composition and hadronic interactions studies
shower universality muon signal electromagnetic signal hadronic interactions mass composition
2011/10/20
We present the first results of the application of the recently found universality of behavior of muon signal to electromagnetic (EM) signal ratio with respect to the vertical depth of showers maximum...
Reconstructing signals from noisy data with unknown signal and noise covariance
statistics, information theory, statistical mechanics
2011/10/8
We derive a method to reconstruct Gaussian signals from linear measurements with Gaussian noise. This new algorithm is intended for applications in astrophysics and other sciences. The starting point ...
A High Signal-to-Noise Ratio Composite Spectrum of Gamma-ray Burst Afterglows
Galaxies high-redshift gamma rays bursts
2010/11/10
We present a composite spectrum of 60 long duration gamma-ray burst (GRB) afterglows with
redshifts in the range 0.35 < z < 6.7 observed with low resolution optical spectra. The composite spectrum co...
GMRT observation towards detecting the Post-reionization 21-cm signal
GMRT the Post-reionization 21-cm signal
2011/1/10
We have analyzed 610 MHz GMRT observations towards detecting the redshifted 21-cm signal from z=1.32. The multi-frequency angular power spectrum C_l(Delta nu) is used to characterize the statistical p...
Dirac neutrino magnetic moment and a possible time evolution of the neutrino signal from a supernova
High Energy Astrophysical Phenomena (astro-ph.HE) High Energy Physics - Phenomenology (hep-ph)
2010/12/23
We analyze the influence of neutrino helicity conversion, $\nu_L \to \nu_R$, on the neutrino flux from a supernova caused by the interaction of the Dirac neutrino magnetic moment with a magnetic field...
Real-Time Signal Processor for Pulsar Studies
neutron pulsars interstellar medium: dispersion Faraday rotation telescope
2009/5/20
This paper describes the design, tests and preliminary results of a real-time parallel signal processor built to aid a wide variety of pulsar observations. The signal processor reduces the distortions...
HI Fluctuations at Large Redshifts: III – Simulating the Signal Expected at GMRT
Cosmology large scale structures radiation
2009/5/19
We simulate the distribution of neutral hydrogen (HI) at
the redshifts z D 1:3 and 3:4 using a cosmological N-body simulation
along with a prescription for assigning HI masses to the particles. The...
HI Fluctuations at Large Redshifts：II – the Signal Expected for theGMRT
Cosmology large scale structures
2009/5/18
For the GMRT, we calculate the expected signal from redshifted
HI emission at two frequency bands centered at 610 and 325MHz.
The study focuses on the visibility-visibility cross-correlations, propo...
