Microquasars as heating sources of the intergalactic medium during reionization of the Universe [PDF]
, 2017 The effect of the primeval sources of radiation and particles on the thermodynamical state of the intergalactic medium during the epoch of reionization is still unclear.

Intergalactic medium metal enrichment through dust sputtering [PDF]
, 2005 We study the motion of dust grains into the intergalactic medium (IGM) around redshift z = 3, to test the hypothesis that grains can efficiently pollute the gas with metals through sputtering.

, 2021 We present a model where some proportion of extraterrestrial civilizations expand uniformly over time to reach a cosmological scale. We then ask what humanity could infer if a sky survey were to find zero, one, or more such civilizations. We show how the results of this survey, in combination with an approach to anthropics called the Self Indication ...

, 2022 In extension to author’s previous work which was embedded in two poems included inside the book “Scientific Poetry” published by “notionpress” Chennai, India. The author extrapolates a theory of human revitalization through long walks and in extension, infinite loops of walks, which was the story of myths by let’s say Swami Prahlad’s long walks without

Quantifying AGN-driven metal-enhanced outflows in chemodynamical simulations [PDF]
, 2015 We show the effects of AGN-driven outflows on the ejection of heavy elements using our cosmological simulations, where super-massive black holes originate from the first stars.

MAGNETIZED JETS DRIVEN BY THE SUN: THE STRUCTURE OF THE HELIOSPHERE REVISITED [PDF]
, 2014 The classic accepted view of the heliosphere is a quiescent, comet-like shape aligned in the direction of the Sun’s travel through the interstellar medium (ISM) extending for thousands of astronomical units (AUs).

Neutrino Oscillations and Decoherence in Short-GRB Progenitors [PDF]
Astrophysical Journal, 2019 Neutrinos are produced in cosmic accelerators, like active galactic nuclei, blazars, supernova remnants and gamma-ray bursts (GRBs). On their way to the Earth they experience flavor oscillations.

How Far Do Cosmic Rays Travel [PDF]
, 1933 Two entirely different suggestions have been advanced in the literature as to where the cosmic rays originate. The first suggestion is that cosmic rays are of local origin (upper earth atmosphere, our own planetary system, etc.).

Power and the Aerial Sublime in Victor Pelevin
The Russian Review, Volume 82, Issue 4, Page 582-598, October 2023., 2023 Abstract This essay distinguishes flight as a salient trope throughout multiple Pelevin texts: Omon Ra (1992), Chapaev and the Void (1996), Generation P (1999), Empire V (2006), and Love for Three Zuckerbrins (2014). It examines flight through the aesthetics of the sublime—classical, (post)‐Soviet, and postmodern.
