Back-action from inertial and non-inertial Unruh-DeWitt detectors revisited in covariant perturbation theory

Adam S. Wilkinson, Leo J. A. Parry, Jorma Louko +1

We investigate the back-action from a spatially pointlike particle detector on a quantum scalar field, as characterised by the expectation value of the field's stress-energy tensor…

Extending Weinberg's EFT: effective scalar-tensor theories up to sixth order

Eugeny Babichev, Sukŗti Bansal, Maria Mylova +1

We present a systematic construction of the six-derivative effective scalar-tensor theories, extending the four-derivative framework previously developed by Steven Weinberg. The on…

Kennicutt-Schmidt relation of galaxies over 13 billion years in the COLIBRE hydrodynamical simulations

Claudia del P. Lagos, Joop Schaye, Matthieu Schaller +16

We investigate the correlation between star formation rate (SFR) surface density and gas surface density (known as the Kennicutt-Schmidt, KS, relation) at kiloparsec (kpc) scales a…

Flexible Gravitational-Wave Parameter Estimation with Transformers

Annalena Kofler, Maximilian Dax, Stephen R. Green +6

Gravitational-wave data analysis relies on accurate and efficient methods to extract physical information from noisy detector signals, yet the increasing rate and complexity of obs…

Multiphase Astrophysics to Unveil the Virgo Environment (MAUVE)

Barbara Catinella, Luca Cortese, Jiayi Sun +26

The Multiphase Astrophysics to Unveil the Virgo Environment (MAUVE) project is a multi-facility programme exploring how dense environments transform galaxies. Combining a VLT/MUSE…

Variability-selected AGN in dwarf galaxies: the incidence of AGN in dwarf and massive galaxies is similar

S. Kaviraj, D. De Cicco, I. Lazar +4

We use the VST-COSMOS survey to identify, via their optical broadband variability, 30 AGN in nearby (z<0.4) dwarf (10^8 MSun < M < 10^10 MSun) galaxies. VST-COSMOS offers a 1 deg^2…
