Constraining the shape of dark matter haloes using only starlight II. Tests of the technique with objects of known gravitational potential

Jorge Sanchez Almeida, Angel R. Plastino, Sergio Guerra Arencibia +2

The paper validates a photometry‑based Eddington Inversion Method (EIM‑tool) that tests whether observed stellar distributions are physically consistent with cuspy or cored dark‑ma…

Euclid Quick Data Release (Q1). The first Euclid view of Planck galaxy protocluster candidates at cosmic noon

Euclid Collaboration, T. Dusserre, H. Dole +339

[ABRIGED ABSTRACT] A large catalogue of candidate galaxy protoclusters with high star-formation rates was produced by the Planck collaboration. We search, in the first data release…

astro-ph.HE2026

First detection of VHE gamma-ray signal from the FSRQ TON 0599

MAGIC Collaboration, K. Abe, S. Abe +245

TON\,0599 (z=0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, \,GeV) gamma-ray band. Its redshift makes it currently o…

GRB 221009A: Observations with LST-1 of CTAO and Implications for Structured Jets in Long Gamma-Ray Bursts

LST Collaboration, K. Abe, S. Abe +328

GRB 221009A is the brightest gamma-ray burst (GRB) observed to date. Extensive observations of its afterglow emission across the electromagnetic spectrum were performed, providing…

astro-ph.SR2026

An eclipsing 8.56 minute orbital period mass-transferring binary

Emma T. Chickles, Joheen Chakraborty, Kevin B. Burdge +34

We report the discovery of ATLAS J101342.5-451656.8 (hereafter ATLAS J1013-4516), an 8.56 minute orbital period mass transferring AM Canum Venaticorum binary with mean Gaia magnitu…

Constraints on dark matter models from the stellar cores observed in ultra-faint dwarf galaxies: Self-interacting dark matter

Jorge Sanchez Almeida

It has been proposed that the stellar cores observed in ultra-faint dwarf (UFD) galaxies reflect underlying dark matter (DM) cores that cannot be formed by stellar feedback acting…
