Core-Collapse Supernova detections from Einstein Telescope within the Milky Way

I. F. Giudice, A. L. De Santis, M. T. Botticella +6

Core-collapse supernovae are key drivers of galaxy evolution and promising sources of gravitational waves, which provide a unique probe of the physics driving their explosion mecha…

Constraining inhomogeneities and asymmetries in SNe, FBOTs, and other high-energy transients from unresolved radio observations

Fabio De Colle, Rosa L. Becerra, Lizeth A. Meza +7

Synchrotron emission in high-energy transients is produced by relativistic electrons accelerated by shocks. As high-energy transients are often unresolved even on angular scales pr…

No evidence for dynamical dark energy from the Combo correlation of GRBs

Marco Muccino, Massimo Della Valle, Luca Izzo +1

Recently, the Dark Energy Spectroscopic Instrument (DESI) collaboration has presented results indicating that dark energy may exhibit dynamical behavior. Calibrated gamma-ray burst…

The Hubble Constant from Blue Type Ia Supernovae

Christa Gall, Luca Izzo, Radoslaw Wojtak +1

There is a persistent tension of about between the value of the Hubble constant, as derived from the local distance ladder vs. the cosmic microwave background, signaling…

Tightening Cosmological Constraints Within and Beyond CDM Using Gamma-Ray Bursts Calibrated with Type Ia Supernovae

Wei Hong, Luca Izzo, Massimo Della Valle +3

Context. Gamma-ray bursts (GRBs) reach redshifts beyond Type Ia supernovae (SNe Ia) and can extend distance measurements into the early Universe, but their use as distance indicato…

AT 2024ahzi: A Type IIP Supernova Discovered by the LSST Commissioning Camera

Kaylee de Soto, V. Ashley Villar, Jared A. Goldberg +25

As part of its commissioning, the Vera C. Rubin Observatory observed several fields repeatedly for a month with ComCam, an instrument that uses the same hardware as the LSST camera…
