Magnetization of the intergalactic medium in the IllustrisTNG simulations: the importance of extended, outflow-driven bubbles [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We study the effects of galaxy formation physics on the magnetization of the intergalactic medium (IGM) using the IllustrisTNG simulations. We demonstrate that large-scale regions affected by the outflows from galaxies and clusters contain magnetic ...

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.

Intergalactic Medium Dispersion Measures of Fast Radio Bursts Estimated from IllustrisTNG Simulation and Their Cosmological Applications [PDF]
, 2020 Fast radio bursts (FRBs) are millisecond-duration radio transients and can be used as a cosmological probe. However, the dispersion measure (DM) contributed by the intergalactic medium (IGM) is hard to distinguish from other components. In this paper, we

Lyman-α transmission properties of the intergalactic medium in the CoDaII simulation [PDF]
Monthly notices of the Royal Astronomical Society, 2020 The decline in abundance of Lyman-α (Lyα) emitting galaxies at z ≳ 6 is a powerful and commonly used probe to constrain the progress of cosmic reionization.

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.
