The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, the short gamma-ray burst GRB 170817A, heralded the birth of multimessenger astronomy. The detection of TeV emission from GRBs motivates follow-up observations with the

Aims. We investigated whether combining gas and stellar kinematic maps provides measurable advantages in recovering galaxy mass profiles compared to using single-component maps alone. We used deep learning models to leverage this joint information. Methods. We developed a probabilistic convolutional neural network (CNN) framework trained and tested

Context. Be/X-ray binaries, the most common class of high-mass X-ray binaries, are characterised by OBe companions, but they display a rich variety of X-ray behaviours. One of the most atypical systems is X0726−260, which also has the earliest optical counterpart among the whole Milky Way and Magellanic Cloud sample. Aims. We intend to improve the

Context. The characterisation of exoplanetary systems depends on the accurate determination of host star parameters. The Ariel mission will probe the atmospheres of a statistically significant sample of exoplanets, and so requires a precise characterisation of the stellar properties well before its launch in 2031. The homogeneous determination of

Transient low-mass X-ray binaries (LMXBs) are usually first detected by all-sky X-ray monitors when they enter new outbursts. These detections typically occur at X-ray luminosities above ∼10 36 erg/s. Observations of these sources during the early rise of the outbursts have therefore been very limited so far. However, the launch of the Einstein

As planetary nebulae evolve, they fade and dissipate into the surrounding interstellar medium, which makes them harder to detect. Modern, advanced amateur equipment can help to uncover this hidden population of ancient 'ghost' planetary nebulae. Via careful processing of long-integration, narrow-band imagery with modest aperture telescopes at a
