SN Helios: A Multiply Imaged Type II Supernova Opening Time-Delay Cosmography beyond redshift of 3

Seiji Fujimoto, Conor Larison, Justin D. R. Pierel +64

We report the discovery and spectroscopic confirmation of SN Helios, a strongly lensed, multiply imaged Type II supernova (SN) at behind the galaxy cluster RXC J0018.5+162…

Constraints on the Pop III Sky Surface Brightness from High-Redshift Caustic Transients in MACS0416

Jakob P. Perivolotis, Pietro Bergamini, Rogier A. Windhorst +18

Population III (Pop III) stars are hypothetical zero-metallicity stellar structures formed from primordial hydrogen and helium. They are theorized to span a wide mass range, extend…

How can we finally see the first light? Status and perspective in the search for Population III stars

Alessandra Venditti, Daniel Schaerer, Erik Zackrisson +26

Finding the first (Population III or Pop III) stars is one of the fundamental quests of astronomy, aiming to deliver the missing link in how stars form at early cosmic times. Yet t…

Project Hephaistos -- III. Characterizing anomalous infrared sources identified as Dyson-sphere candidates

Andreas J. Korn, Matías Suazo, Erik Zackrisson +3

The infrared-flux excess of stars harbouring Dyson spheres represent one potential technosignature of extraterrestrial intelligence. In a previous Project Hephaistos paper, we high…

Project Hephaistos -- IV. James Webb Space Telescope Observations of Two Dyson Sphere Candidates

Erik Zackrisson, Arjan Bik, Anita Ali Asgar +11

We report on JWST/MIRI imaging and spectroscopy of two M-dwarf stars previously singled out by project Hephaistos as potential Dyson-sphere candidates (their candidates D and E) du…

The impact of stellar binaries and star cluster dynamics on pair-instability supernovae

Francesco Gabrielli, Cristiano Ugolini, Lavinia Paiella +12

Pair-instability supernovae (PISNe) are among the most luminous transients in the Universe. However, they have never been confidently observed. Solving this puzzle would have key i…
