The impact of nuclear equations of state on the dynamics and multi-messenger emission of magnetorotational stellar explosions
Andrea Celati, Matteo Bugli, Luca Del Zanna +2
The gravitational collapse of massive stars at the end of their life leads to powerful supernova explosions that produce compact objects, regulate the dynamics of host galaxies, an…
Shape Coexistence in Zr from a Model-Independent Analysis
N. Marchini, M. Rocchini, M. Zielinska +33
Low-lying states of Zr were investigated via low-energy multi-step Coulomb excitation. From the measured -ray yields, \textcolor{black}{16} reduced \textcolor{black}{E2}…
Correcting the fiber-aperture bias affecting galaxy stellar populations in the Sloan Digital Sky Survey. Aperture corrections to absorption indices based on CALIFA integral field observations
Stefano Zibetti, Jacopo Pratesi, Anna R. Gallazzi +2
Stellar population properties are crucial for understanding galaxy evolution. Their inference for statistically representative samples requires deep multi-object spectroscopy, typi…
Euclid: Quick Data Release (Q1) -- Dual AGN in low-mass galaxies
M. Mezcua, B. Laloux, M. Scialpi +164
Dual active galactic nuclei (AGNs) are expected in hierarchical galaxy evolution models, in which low-mass galaxies merge to build more massive ones. While observational evidence f…
IXPE view of the Crab pulsar following the 17 July and 6 August 2025 glitches
Paolo Soffitta, Niccolò Bucciantini, Josephine Wong +19
The Crab pulsar experienced two relatively small glitches separated by only 20 days in September and October 2025. IXPE observed the source twice, with delay times since the glitch…
Euclid Quick Data Release (Q1): Euclid spectroscopy of quasars. 1. Identification and redshift determination of 3500 bright quasars
Euclid Collaboration, Y. Fu, R. Bouwens +354
The slitless spectroscopy mode of the NISP onboard Euclid has enabled efficient spectroscopy of objects within a large FoV. We present a large and homogeneous sample of bright quas…
