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.

From Wood Chuck Holes to Worm Holes—A Look into the Notebooks of John A. Wheeler
Annalen der Physik, Volume 534, Issue 8, August 2022., 2022 This article offers an introduction to the notebooks of the American physicist John Archibald Wheeler (1911–2008) and argues that they represent a unique historical source. Several salient features of these notebooks are highlighted by following the example of the emergence of the concept of a “wormhole,” one of Wheeler's most famous ideas.

Providence and the magnitude of the universe
Dialog, Volume 61, Issue 2, Page 96-101, Summer 2022., 2022 Abstract Why did God create a vast universe? Various answers are discussed and rejected: (a) for its beauty; (b) to instill a sense of the sublime in his intelligent creatures; (c) to demonstrate his glory, (d) to provide a home for extraterrestrial species; (e) to guarantee that the natural emergence of (intelligent) life, though extremely rare ...

THE RE‐DISCOVERY OF CONTEMPLATION THROUGH SCIENCE
Zygon®, Volume 56, Issue 3, Page 758-776, September 2021., 2021 Abstract Some of the early‐modern changes in the social framing of science, while often believed to be essential, are shown to be contingent. They contribute to the flawed public narrative around science today, and especially to the misconceptions around science and religion.

Cosmic neutrino flux and spin flavor oscillations in intergalactic medium [PDF]
Phys. Lett. B 839 (2023) 137791, 2022 The ultra high energy (UHE) cosmic neutrinos are expected to play a pivotal role in the disquisition of physics beyond the standard model of particle physics as well as serve as an ideal cosmic messengers. This epitomizes the selling point of several currently running or planned neutrino telescopes.

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.

Secondary GeV-TeV emission from ultra-high-energy cosmic rays accelerated by GRB 221009A [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2023,
Volume 519, Issue 1, L85-L86, 2022 The origin of ultra-high-energy cosmic rays (UHECRs) remains elusive. Gamma-ray bursts (GRBs) are among the best candidates able to meet the stringent energy requirements needed for particle acceleration to such high energies. If UHECRs were accelerated by the central engine of GRB 221009A, it might be possible to detect secondary photons and neutrinos

Heavy elements are intergalactic travelers [PDF]
Science, 2017 Galaxy Evolution All elements heavier than helium are made in stars, which can eject them in a supernova explosion. In small dwarf galaxies, a single supernova has enough energy to completely expel enriched gas out of the galaxy and into the intergalactic medium. Angles-Alcazar et al.
