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.

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.

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.

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.

, 2021 In 1982, MIT physicist Frank Wilczek predicted and named ANYONS, quasiparticles (particle-like formations) that are confined to 2 dimensions and were discovered in 2020. The name might come from Prof. Wilczek's lighthearted comment "anything goes".

On The Nature of Tachyons and The Pioneer Anomaly
International Journal Of Scientific Advances, 2023 One considers tachyon repulsive force f from intergalactic space, by Takaaki Musha, as responsible for the rotation speed of galaxies, as not due to dark matter.

Interactions of Cosmic Rays around the Universe. Models for UHECR data interpretation
EPJ Web of Conferences, 2017 Ultra high energy cosmic rays (UHECRs) are expected to be accelerated inastrophysical sources and to travel through extragalactic space before hitting the Earth atmosphere.

ANISOTROPIC GALACTIC OUTFLOWS AND ENRICHMENT OF THE INTERGALACTIC MEDIUM. II. NUMERICAL SIMULATIONS [PDF]
, 2010 We combine an analytic model for anisotropic outflows and galaxy formation with numerical simulations of large-scale structure and halo formation to study the impact of galactic outflows on the evolution of the intergalactic medium (IGM).
