Galactic Winds [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2005
Galactic winds are the primary mechanism by which energy and metals are recycled in galaxies and are deposited into the intergalactic medium. New observations are revealing the ubiquity of this process, particularly at high redshift.

Power and the Aerial Sublime in Victor Pelevin

open access: yesThe 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

open access: yesAstronomische 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

open access: yesAstronomische 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

open access: yesScience 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

open access: yesAdvances 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.

Modeling and Optimization of Infrared-Convection Drying Parameters and Slice Thickness of Onion Slices: Effects on Drying Kinetics and Physicochemical Quality. [PDF]

open access: yesFood Sci Nutr
This assessment focused on drying time, color, shrinkage, water activity, and rehydration ratio. Onion slices were dried using infrared powers 1500, 3500, and 5500 W/m2, airflow rates 0.3, 0.7, and 1.0 m/s, and thicknesses 4, 6, and 8 mm. Midilli and Kucuk most effectively improved the drying process of onion slices in a thin layer.

Effective Screening due to Minihalos During the Epoch of Reionization [PDF]

open access: yes, 2002
We show that the gaseous halos of collapsed objects introduce a substantial cumulative opacity to ionizing radiation, even after the smoothly distributed hydrogen in the intergalactic medium has been fully reionized. This opacity causes a delay of around
