First generation of quasars [PDF]

Nature, 2010
The discovery of two quasars in the distant Universe that apparently have no hot dust in their environments provides evidence that these systems represent the first generation of their family.

GRAVITY GENERATION OF ELECTROMAGNETIC RADIATION AND THE LUMINOSITY OF QUASARS

Modern Physics Letters A, 1998
A mechanism is proposed for the emission of radiation by charged particles in the gravitational field of a quasar whereby the gravitational field is coupled directly to the radiation field of the charge via the principle of equivalence. A generalized Larmor formula for the radiation emitted by a charge at rest in a gravitational field can account for ...

The DACs and SACs Effects From Stars to Quasars. Some First General Notices [PDF]

AIP Conference Proceedings, 2007
The spectra of Hot Emission Stars and AGNs present peculiar profiles that result from dynamical processes such as accretion and/or ejection of matter from these objects. In this paper we explain the idea of DACs and SACs phenomena, as a reason of spectral lines peculiarity in Hot Emission Stars and AGNs.

A gravity generation of electromagnetic radiation and the luminosity of quasars

Il Nuovo Cimento B, 1972
In this paper a new mechanism is proposed for the omission of radiation by charged particles in a gravitational field whereby the gravitational field is coupled directly to the radiation field of the charge via the principle of equivalence. This leads to a Larmor formula for the electromagnetic power emitted by a charge at rest (on the average) in a ...

A General Outlook on the Quasars

1968
Since my main field of research is astrophysics, I suppose that when asking me to present this paper, Professor Ramakrishnan probably intended to stress the point that the Institute of Mathematical Sciences, which is so rapidly and vigorously developing from year to year, after having extended the domain of its activities from theoretical physics to ...

Problems of Magnetic Field Generation in Galactic Nuclei, Quasars and Radiogalaxies

1988
The recurring theme of the preceding chapters are magnetic fields that permeate the discs of spiral galaxies and their immediate surroundings. In many ways, still more fascinating are the magnetic phenomena in other astronomical species of galactic order: nuclei of galaxies, quasars and radiogalaxies.

Inspiring the next generation of scientists with their observations of quasars, black holes, Jupiter, and SETI with the Goldstone Apple Valley Radio Telescope, GAVRT

Astronomy Reports, 2017
This paper describes a radio astronomy programfor schools, the Goldstone-AppleValley Radio Telescope,GAVRT. The GAVRT program is designed to bring the inspiration and enthusiasm to a younger generation of teachers and children who learn about science by doing real science, just as Iosif Shklovsky brought to an older generation.

The 1905 Einstein equation in a general mathematical analysis model of quasars

2010
The 1905 wave equation of Albert Einstein is a model that can be used in many areas, such as physics, applied mathematics, statistics, quantum chaos and financial mathematics, etc. I will give a proof from the equation of A. Einstein’s paper “Zur Elektrodynamik bewegter Körper†it will be done by removing the variable time (t) and the constant (c)
