Astronomers from Chile Studies Gas-Churning Monster Black Holes – Claudio Ricci participated

An international group of astronomers, led by Lorena Hernández-García and with the participation of Diego Portales University astronomer Claudio Ricci, have discovered for the first time the signal of a pair of gigantic black holes perturbing a cloud of gas at the center of a galaxy, using observations from NASA’s Neil Gehrels Swift Observatory. “It’s …

Chilean Astronomers see a massive black hole awaken in real time – Claudio Ricci and Roberto Assef participated.

In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), to track how the galaxy’s brightness has varied. In a study out today, they conclude that they …

Estrella fugitiva podría explicar la desaparición de un agujero negro

La señal de que el agujero negro se estaba alimentando de gas desapareció, quizás cuando una estrella interrumpió su banquete. Este evento podría entregar nueva información sobre estos misteriosos objetos. En el centro de una galaxia lejana, un agujero negro consume lentamente un disco de gas que da vueltas entorno a él, como agua drenándose …

Astronomers Unveil Growing Black Holes in Colliding Galaxies

An international team of researchers, including Claudio Ricci, professor of the Nucleo de Astronomia, performed the largest survey of the cores of nearby galaxies in near-infrared light, using high-resolution images taken by NASA’s Hubble Space Telescope and the W. M. Keck Observatory in Hawaii. The Hubble observations represent over 20 years’ worth of snapshots from …
