Imprints of the super-Eddington accretion on the quasar clustering
, 2017 Super-Eddington mass accretion has been suggested as an efficient mechanism to grow supermassive black holes (SMBHs). We investigate the imprint left by the radiative efficiency of the super-Eddington accretion process on the clustering of quasars using ...

Redshift Dependent Lag-Luminosity Relation in 565 BASTE Gamma Ray Bursts
, 2007 We compared redshifts $z_Y$ from Yonetoku relation and $z_{lag}$ from the lag-luminosity relation for 565 BASTE GRBs and were surprised to find that the correlation is very low.

LUMINOSITIES OF RADIO PULSARS [PDF]
International Journal of Modern Physics D, 2013 Luminosity is an intrinsic property of radio pulsars related to the properties of the magnetospheric plasma and the beam geometry, and inversely proportional to the observing frequency. In traditional models, luminosity has been considered as a function of the spin parameters of pulsars.

Luminosity Profiles of Merger Remnants
, 1999 Using published luminosity and molecular gas profiles of the late-stage mergers NGC 3921, NGC 7252 and Arp 220, we examine the expected luminosity profiles of the evolved merger remnants, especially in light of the massive CO complexes that are observed ...
