A MIKE + UVES survey of Sub-Damped Lyman-Alpha Systems at z<1.5

Joseph D. Meiring, James T. Lauroesch, Varsha P. Kulkarni +3

We have combined the results from our recent observations of Damped and sub-Damped Lyman-alpha systems with the MIKE and UVES spectrographs on the Magellan Clay and VLT Kueyen tele…

Brans-Dicke Theory and primordial black holes in Early Matter-Dominated Era

Bibekananda Nayak, Lambodar Prasad Singh

We show that primordial black holes can be formed in the matter-dominated era with gravity described by the Brans-Dicke theory. Considering an early matter-dominated era between in…

Accretion, Primordial Black Holes and Standard Cosmology

Bibekananda Nayak, Lambodar Prasad Singh

Primordial Black Holes evaporate due to Hawking radiation. We find that the evaporation time of primordial black holes increase when accretion of radiation is included.Thus dependi…

A Dual Four Dimensional Superstring

B. B. Deo, P. K. Jena

The 26 dimensional bosonic string, first suggested by Nambu and Goto, is reduced to a four dimensional superstring by using two species of 6 and 5 Majorana fermions as proposed by…

New Magellan Inamori Kyocera Echelle Observations of z<1.5 sub-damped Lyman-alpha systems

Joseph D. Meiring, Varsha P. Kulkarni, James T. Lauroesch +3

The Damped and sub-Damped Lyman-alpha (DLA and sub-DLA) systems seen in the spectra of QSOs offer a unique way to study the interstellar medium of high redshift galaxies. In this p…

Effect of accretion on primordial black holes in Brans-Dicke theory

B. Nayak, A. S. Majumdar, L. P. Singh

We consider the effect of accretion of radiation in the early universe on primordial black holes in Brans-Dicke theory. The rate of growth of a primordial black hole due to accreti…
