Descripción
Neutral atomic hydrogen (HI) is a crucial component of the Milky Way and a protagonist in the cycles of energy and matter that lead to the formation of stars. I will present a study of the filamentary structure identified in the HI emission at 21 cm using the HI4PI and the HI/OH/Recombination-line (THOR) surveys of the Galactic plane. We found that the Milky Way’s disk regions beyond ten kiloparsecs and up to roughly 18 kiloparsecs from the Galactic center display HI filamentary structures predominantly parallel to the Galactic plane. However, we also found that the HI filaments are mostly perpendicular or do not have a preferred orientation with respect to the Galactic plane for regions at lower Galactocentric radii. Using the insight from numerical simulations, we interpret these results as the imprint of supernova feedback in the inner Galaxy. We also studied the carbon monoxide (CO) emission observations from The Milky Way Imaging Scroll Painting (MWISP) survey. We found that the orientations of the filamentary structures traced by CO emission differ from those in the HI emission. We interpret this result as indicating that the molecular structures do not simply inherit these properties from parental atomic clouds. Instead, they are shaped by local physical conditions, such as stellar feedback, magnetic fields, and Galactic spiral shocks.
The problem of forming supermassive black holes (SMBHs) with masses up to a billion solar masses at redshifts close to the dawn of galaxy and stellar formation is exacerbated by their daily observations from the James Webb Space Telescope (JWST). I discuss a novel channel of SMBH formation due to the gravitational collapse of superdense structures of dark matter made of sub-MeV fermions. I...
In this contribution, we present a study of the chaotic behavior of geodesics in an approximate spacetime with a magnetic dipole and mass quadrupole.
The chaotic behavior of geodesics is a key aspect of understanding the underlying structure and dynamics of astrophysical systems.
This spacetime was derived from the Kerr-Newman metric by incorporating the mass quadrupole and the magnetic...
Los avances tecnológicos nos ofrecen la oportunidad de vivir una era extraordinaria para la Astrofísica Relativista con una profusión de datos observacionales [1, 2]. La Relatividad General se consolida como la teoría más precisa para explicar estas nuevas observaciones. Lo que alguna vez se consideró una curiosidad matemática, como los agujeros negros y las ondas gravitacionales, se ha...
El Volcan Cerro Machín es un estratovolcán activo compuesto por un edificio volcánico y varios domos, ubicado en zona rural de la ciudad de Ibagué, departamento del Tolima en el centro de Colombia. Por su historia eruptiva es uno de los volcanes más peligrosos del país. Existe una comunidad de tamaño apreciable que vive en la zona de influencia de este volcán, increiblemente algunos viven...
