Abstract We develop a general data-driven and template-free method for the extraction of event waveforms in the presence of background noise. Recent gravitational-wave observations provide one of the significant scientific areas requiring data analys

The effect of variation of stellar dispersion velocities by the galactic latitude in interpreting gravitational microlensing observations

Autor: S sajadian, S Rahvar

Publikováno v: Iranian Journal of Physics Research, Vol 19, Iss 2, Pp 391-395 (2019)

Our galaxy is a spiral galaxy and its stars are mostly in a thin disk and rotate around the galactic center. The vertical component of the dispersion velocity of stars is a function of the galactic latitude and decreases with increasing it. In the ga

HATS-18b is a transiting planet with a large mass and a short orbital period, and is one of the best candidates for the detection of orbital decay induced by tidal effects. We present extensive photometry of HATS-18 from which we measure 27 times of
