Unraveling the role of merger histories in the population of Insitu stars: linking IllustrisTNG cosmological simulation to H3 survey

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Razieh Emami, Lars Hernquist, Randall Smith, James F. Steiner, Grant Tremblay | Summary: We undertake a comprehensive investigation into the distribution of insitu stars within Milky Way-like galaxies, leveraging TNG50 simulations and comparing their predictions with data from the H3 survey. Our analysis reveals that 28% of […]

Investigating the interplay between AGN coronal properties and hard X-ray variability with NuSTAR

Kavli Affiliate: Claudio Ricci | First 5 Authors: Roberto Serafinelli, Alessandra De Rosa, Alessia Tortosa, Luigi Stella, Fausto Vagnetti | Summary: Active galactic nuclei (AGN) are extremely variable in the X-ray band down to very short time scales. However, the driver of the X-ray variability is still poorly understood. Previous results suggest that the hot […]
