The surface-brightness profiles of galaxy disks fall into three main classes, based on whether they are simple exponentials (Type I), bend down at large radii...
Triaxiality can Explain the Alleged Dark Matter Deficiency in some Dwarf Galaxies
Dark Matter (DM) is an ingredient essential to the current cosmological concordance model. It provides the gravitational pull needed for the baryons to form...
Triggering of Cloud Collapse in a Galactic Disk by Infall of a High Velocity Cloud
We express in linearized form the five classical coupled equations representing the rotating gas disk of a standard disk galaxy. We solve them in three limiting...
Triple-Double Radio Galaxies: Clues for understanding recurrent AGN activity
Using LOFAR Two-metre Sky Survey (LoTSS), we discovered three cycles of episodic jet activity (J1225+4011, Chavan et al. 2023, MNRAS) in a giant radio galaxy...
Tropospheric wind regimes and site topography effects: importance for site characterization
Roque de los Muchachos Observatory (ORM) at La Palma (Canary Islands) is one of the two top sites selected for hosting the future European Large Telescope (ELT)...
