We extend the catalogue of "phenomenologically preferred" hadronic axion models to include heavy fermion representations associated with higher-dimensional decay operators. The latter have recently been shown to self-consistently trigger a period of

The majority of the baryonic matter in the universe is in the form of astrophysical plasmas. The mass of the hot X-ray emitting gas in a cluster of galaxies has more mass than the galaxies in the cluster. With the launch of the XRISM microcalorimeter

We present a simple, yet powerful column density diagnostic for plasmas enabled by X-ray microcalorimeter observations. With the recent developments of the spectral simulation code Cloudy, inspired by the high spectral resolution of XRISM and Athena,

BabyIAXO is the intermediate stage of the International Axion Observatory (IAXO) to be hosted at DESY. Its primary goal is the detection of solar axions following the axion helioscope technique. Axions are converted into photons in a large magnet tha

Detections of fast X-ray transients (FXTs) have been accrued over the last few decades. However, their origin has remained mysterious. There is now rapid progress thanks to timely discoveries and localisations with the Einstein Probe mission. Early r

Optical spectra of the Very Late Thermal Pulse (VLTP) object V4334 Sgr have shown a rapidly changing spectrum resulting from shocks in the outflow, which created a new bipolar nebula inside the old nebula. We see C II and C III emission lines emergin

Exposure bias is a well-known issue in recommender systems where items and suppliers are not equally represented in the recommendation results. This bias becomes particularly problematic over time as a few items are repeatedly over-represented in rec

The very late thermal pulse (VLTP) affects the evolution of $\sim$20\% of 1--8\,$\mathrm M_\odot$ stars, repeating the last phases of the red giant within a few years and leading to the formation of a new, but hydrogen-poor nebula within the old plan

Should dark matter (DM) axions be discovered in a haloscope, follow-up experiments will be necessary to break the degeneracy between the axions' coupling to photons and their local DM abundance. Given that a discovery would justify more significant i

Black hole (BH) superradiance can provide strong constraints on the properties of ultralight bosons (ULBs). Since most of the previous work has focused on the theoretical predictions, here we investigate the most suitable statistical framework to con
