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…

Linking simulations and observations of star-forming regions I. Masses and temperatures of ALMAGAL-like cores

Birka Zimmermann, Álvaro Sánchez-Monge, Stefanie Walch +1

Dense cores and clumps in massive star-forming regions are studied through (sub-)millimetre continuum observations, but inferred masses and temperatures can be biased by limited re…

Magnetic Fields in Massive Star-forming Regions (MagMaR). IX. Radiative Torque Alignment and Disruption in NGC6334I

Vineet Rawat, Thiem Hoang, Patricio Sanhueza +18

Intense radiation from high-mass stars is expected to significantly affect dust grain alignment and evolution through RAdiative Torques (RATs). We investigate this effect in a mass…

Euclid. A two-point correlation approach to diagnosing star-related systematics in the Euclid spectroscopic survey

Euclid Collaboration, I. Risso, B. R. Granett +298

The Euclid spectroscopic survey will measure galaxy clustering with unprecedented precision, requiring stringent control of observational and instrumental systematics. Star-related…
