Proceedings of the International Astronomical Union, 2005 The absorption lines seen in the spectra of high redshift QSOs are important tools for studying the early evolution of galaxies and intergalactic medium. In this presentation I briefly review various available observations, our understanding of different

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.

Revisiting the emission line source detection problem in integral field spectroscopic data
Astronomische Nachrichten, Volume 344, Issue 5, June 2023., 2023 Abstract We present a 3‐dimensional matched filtering approach for the blind search of faint emission‐line sources in integral‐field spectroscopic datasets. The filter is designed to account for the spectrally rapidly varying background noise due to the telluric air glow spectrum.

Effect of the metallicity of the intergalactic medium in the Lyman‐α forest correlation function
Astronomische Nachrichten, Volume 344, Issue 1-2, January-February 2023., 2023 Abstract The Lyman‐α (Lyα) forest allows to constraint cosmological parameters at redshifts above 1.8$$ 1.8 $$ using the technique of standard rulers determined by baryon acoustic oscillations. This makes it an important tracer for the study of the universe at high redshift.

The trouble with STEAM and why we use it anyway
Science Education, Volume 105, Issue 2, Page 209-231, March 2021., 2021 Abstract As an emerging field of theory, research, and practice, STEAM (Science, Technology, Engineering, Arts, and Mathematics) has received attention for its efforts to incorporate the arts into the rubric of STEM (Science, Technology, Engineering, and Mathematics) learning.

On the Electromagnetic Vacuum Origins of Dark Energy, Dark Matter, and Astrophysical Jets
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We use a semiclassical version of the Nexus paradigm of quantum gravity in which the quantum vacuum at large scales is dominated by the second quantized electromagnetic field to demonstrate that a virtual photon field can affect the geometric evolution of Einstein manifolds or Ricci solitons.

A High-Resolution Study of the High-Redshift Intergalactic Medium [PDF]
, 2007 We present a study of the structure and evolution of the high-redshift intergalactic medium (IGM) using a variety of approaches based on high-resolution quasar spectra.

Dipole distortions in the intergalactic medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Abstract Baryonic feedback can significantly modify the spatial distribution of matter on small scales and create a bulk relative velocity between the dominant cold dark matter and the hot gas. We study the consequences of such bulk motions using two high-resolution hydrodynamic simulations, one with no feedback and one with very strong ...

The Origin of Intergalactic Light in Compact Groups of Galaxies
Universe, 2021 We investigate the origin of intergalactic light (IGL) in close groups of galaxies. IGL is hypothesized to be the byproduct of interaction and merger within compact groups.
