Title: Observing Sagittarius A* with ALMA

Place: DAA Seminar. Jeroni Muñoz Research Building, fourth floor, in Campus de Burjassot.

Day: Tuesday, March 14, 2023. Time: 12:00.

Abstract:

Sagittarius A* is a supermassive black hole in the center of the Milky Way. With the exquisite sensitivity of ALMA we can study the event horizon-scale variability of this system with unprecedented time cadence and signal to noise ratio. I will present the recent findings of the full-Stokes Sagittarius A* light curve analysis and their relation to the observations by the Event Horizon Telescope. I will also discuss the results of the orbital motion model application to the Sagittarius A* linear polarization ALMA light curves at millimeter wavelength, and the emerging theoretical connection to the high energy flaring activity of the system.
