The cosmic web's Lyman- glow at ; hydrodynamic models, dust, and wide-field, narrow-band detection
Oleksii Sokoliuk, John K. Webb, Kenneth M. Lanzetta +12
The diffuse Lyman- glow of the cosmic web has long been predicted but has so far eluded direct detection over cosmologically significant volumes. We construct synthetic Lyman-$…
Science for Peace and the need for Civil Clauses at universities and civilian research institutions
J. Altmann, U. Amaldi, M. Barone +27
After the end of World War II, the commitment to confine scientific activities in universities and research institutions to peaceful and civilian purposes has entered, in the form…
A 70 pc-Diameter Nova Super-remnant Surrounding the Recurrent Nova RS Ophiuchi
Michael M. Shara, Kenneth M. Lanzetta, Alexandra Masegian +9
Recurrent novae undergo thermonuclear-powered eruptions separated by less than 100 years, enabled by subgiant or red giant donors transferring hydrogen-rich matter at very high rat…
UNIONS: The Ultraviolet Near-Infrared Optical Northern Survey
Stephen Gwyn, Alan W. McConnachie, Jean-Charles Cuillandre +86
The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada-France-Hawai'i Telescope, the Pan-STARRS telescopes,…
Gaps in stellar streams as a result of globular cluster fly-bys
Salvatore Ferrone, Marco Montuori, Paola Di Matteo +10
Thin stellar streams, such as those resulting from the tidal disruption of globular clusters, have long been known and used as probes of the gravitational potential of our Galaxy,…
Direct Images of the Cosmic Web of Intergalactic and Circumgalactic Gas in the Distant Universe
Kenneth M. Lanzetta, Stefan Gromoll, Michael M. Shara +5
Most of the baryonic matter of the Universe resides in a highly-ionized gaseous intergalactic medium. This gas flows along dark-matter filaments toward galaxy superclusters, cluste…
