Line surveys of complex molecules with millimeter and sub-millimeter telescopes are important for probing the physical and chemical environments of massive star
One of the most puzzling problems in astrophysics is to understand the anomalous resistivity in collisionless magnetic reconnection that is believed extensively
Recently an f(T) gravity based on the modification of teleparallel gravity was proposed to explain the accelerated expansion of the universe. We use observation
The aim of the paper is to study weak gravitational lensing of quantum(perturbed) and classical lukewarm black holes(QLBHs and CLBHs respectively) in the presen
