The Astrophysics Department of the Astrobiology Center (CAB/CSIC-INTA),
Madrid, Spain, offers a 3-year postdoctoral position to investigate the
connection between star-formation, AGN, and gas outflows/inflows
(feedback) in ultra-luminous infrared galaxies using high-spatial
resolution observations. The successful candidate will work with Dr.
Miguel Pereira-Santaella and his research group.

This ESO Picture of the Week shows the centre of a galaxy named NGC 5643. This galaxy is located 55 million light-years from Earth in the constellation of Lupus (The Wolf), and is known as a Seyfert galaxy. Seyfert galaxies have very luminous centres — thought to be powered by material being accreted onto a supermassive black hole lurking within — that can also be shrouded and obscured by clouds of dust and intergalactic material.

First detection of the 448 GHz H2O transition in space

Water is a key molecule to probe dense and warm regions in the interstellar medium, because of its chemistry as well as its coupling to the far-infrared. This work presents the first detection of the ortho-H2O 4_23 – 3_30 transition at 448 GHz in space. Continue reading →

Dusty doughnut around massive black hole spied for first time

The dust continuum emission at 694 GHz mapped by ALMA in the CND of NGC1068. See García-Burillo et al. 2016 for further details.

The dust continuum emission at 694 GHz mapped by ALMA in the circumnuclear disk of NGC1068. See García-Burillo et al. 2016 for further details.

An international team of astronomers lead by the spanish astronomer Santiago García-Burillo (OAN, Madrid), and with the participation of CAB scientists (Almudena Alonso Herrero and Luis Colina), have been able to resolve for the first time the dusty torus around the massive black hole in the nucleus of the nearby active galaxy NGC 1068.
