Fractal analysis is a powerful tool to study the nature of galaxy distribution. The use of multifractal analysis of the galaxy distribution for the investigation of the transition to homogeneity in the Universe is reviewed. ...

In this study, we investigated the orientation model of Broad Absorption Line (BAL) quasars using a sample of sources that are common in Sloan Digital Sky Survey (SDSS) Data Release (DR)-16 quasar catalogue and Very Large ...

The Franck-Condon factors and r-centroids, which are very closely related to vibrational transition probabilities, have been evaluated by the more reliable numerical integration procedure for the bands of B 2∑+ X 2∑+, F ...

Some of the molecular transitions in UV in sunspots are pointed out and Franck-Condon factors for some of these have been calculated.

The phenomenon of gyroscopic precession is studied within the framework of the Frenet-Serret formalism adapted to quasi-Killing trajectories. Its relation to the congruence vorticity is highlighted with particular reference ...

The frequency drift and time splitting of solar radio bursts are observed with a multi-channel radiometer and a polarimeter at frequencies around 25 MHz. It is found that a majority of noise storm bursts have drift ...

The frequency shifts and line broadening of radiation from the surface of rapidly rotating neutron stars are calculated using a rotationally perturbed interior spherical metric and a representative choice of the equation ...

Propagating slow magneto-acoustic waves are often observed in polar plumes and active region fan loops. The observed periodicities of these waves range from a few minutes to a few tens of minutes and their amplitudes were ...

Context. Solar-like oscillations have now been observed in several stars, thanks to ground-based spectroscopic observations and space-borne photometry. CoRoT, which has been in orbit since December 2006, has observed the ...
