Gas absorption of soft X-rays strongly impacts the redshift distribution of dark Fast X-ray Transients

Abstract The progenitors of many Fast X-ray Transients (FXTs) and those of γ-ray bursts (GRBs) are strongly linked. Given that ”dark” GRBs are typically found to be events suffering from enhanced extinction in the host galaxy, we investigate the nature of ”dark” FXTs. However, un...

Episodic super-Eddington accretion as a clue to Overmassive Black Holes in the early Universe

Abstract Early JWST observations are providing growing evidence for a ubiquitous population of accreting supermassive black holes (BHs) at high redshift, many of which appear overmassive compared to the empirically-derived local scaling relation between black hole mass and host g...

Child and adolescent psychiatry and mental health research "MI VEDETE?" project: a value-based and participatory approach to adolescent mental health in Italian schools

The “MI VEDETE?” (“Do You See Me?”) project explores adolescent mental health, identifying emotional distress and preventing mental health disorders through co-designing the solutions with upper secondary school students, families, and educators within the school environment. The...

Evidence of a massive accretion event 1.8 billion years before the Gaia-Sausage-Enceladus merger

Abstract The merger history of the Galaxy has been traced back firmly to a redshift of 2 (10 billion years ago). While evidence for the existence of at least one more substantial merger before this time has been presented, its interpretation is yet to be fully established. Here w...
