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…

The BUFFALO Survey : The Subhalo Mass Function for Abell 2744 with Strong+Weak Gravitational Lensing

Nency R. Patel, Mathilde Jauzac, Anna Niemiec +16

We present a combined strong and weak gravitational lensing mass model of the massive merging galaxy cluster Abell 2744 (z = 0.308). The mass reconstruction combines strong-lensing…

The assembly history of NGC 1365 through chemical archaeology

Lisa J. Kewley, Kathryn Grasha, Alex Garcia +8

Galaxies build through infalling gas and galaxy mergers. Tracking the dynamical history of a galaxy from a single snapshot in time is notoriously difficult. We show that the dynami…

Emulator-Assisted Calibration of a Semi-Analytic Galaxy Formation Model for the Roman Galaxy Redshift Survey

Andrew Robertson, Andrew Benson

Mock catalogues for the Roman Galaxy Redshift Survey benefit from galaxy populations whose physical properties and emission-line observables are predicted within a single galaxy-fo…

Scaling Relations of Galactic Outflows Across Cosmic Time: New Insights from Cosmic Noon

Tiffany Liou, Xinfeng Xu, Allison L. Strom +8

Galactic outflows play a significant role in regulating galaxy evolution. Scaling relations between stellar mass (), star formation (SFR), and outflow properties have been…

Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign

T. Shenar, J. Bodensteiner, M. Abdul-Masih +73

Massive stars at low metallicity (Z) play a central role in shaping the high-redshift Universe, yet their multiplicity remains poorly constrained. The Binarity at Low Metallicity (…
