Shortening the Baseline: Characterising Type Ia Supernovae Using

Joel M. Velasco, Paolo A. Mazzali, Christopher Ashall +8

An explorative study of Type Ia Supernovae (SNe Ia) light curves is presented. decline-rate metrics are used to evaluate alternative characterisations of light curve di…

Constraints on the VHE counterpart of two binary black hole mergers observed by the MAGIC and CTAO LST-1 telescopes

K. Abe, S. Abe, J. Abhir +358

We present very-high-energy gamma-ray observations of two binary black hole merger candidates, GW240615_113620 and GW241125_010116, performed with the Major Atmospheric Gamma Imagi…

SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss

Qian Zhai, Jujia Zhang, Xiaofeng Wang +51

We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…

Magnetorotational instabilities in solids: Application to neutron-star crusts

Arthur G. Suvorov, Thomas Celora, Kostas D. Kokkotas

The magnetorotational instability can generate strong, turbulent substructure within magnetized shear flows. The efficacy of the mechanism as a function of microphysical aspects of…

Population synthesis of Galactic middle-aged pulsar wind nebulae I. Detection prospects for current and future instruments

A. De Sarkar, D. F. Torres, B. Olmi +2

Pulsar wind nebulae (PWNe) constitute the largest population of Galactic very-high-energy (VHE; GeV) -ray sources and are key laboratories for studying particle accele…

Late-time evolution of the interacting stripped-envelope supernova 2017dio

C. Humina, C. P. Gutiérrez, H. Kuncarayakti +14

The discovery of stripped-envelope supernovae (SNe) interacting with dense circumstellar medium (CSM) challenges our current understanding of massive star evolution. We present lat…
