PublicationThe location of optically thin CO emission in M82
Observations of a broad area at the core of M82, obtained with spatial resolution 30 arcsec and velocity resolution 15.6 km/sec in the J = 2-1 line of CO using...

TalkThe multiple routes of galaxy transformation across the cosmic epochs
In the local universe most of the stellar mass is in passive galaxies, where star formation isabsent or at very low levels. Understanding what are the...

PublicationThe OTELO Survey: The Star Formation Rate Evolution of Low-mass Galaxies
We present the analysis of a sample of Hα, Hβ, and [O II] emission line galaxies from the OTELO survey, with masses typically below $\mathrm{log}({M}_{* }/{M}_{...

PublicationThe starburst galaxy NGC 7714
Narowband H alpha imaging and long-slit optical and near-infrared spectroscopy are analyzed in a study of the starburst galaxy NGC 7714. The data indicate that...

PublicationThe starburst model for active galactic nuclei - The broad-line region as supernova remnants evolving in a high-density medium
The evolution of an SNR in a high-density medium has been studied using analytical and numerical hydrodynamic and photoionization models. The models show that...

TalkThe triggering mechanisms of powerful radio galaxies: mergers and interactions.
Despite speculation that both starburst and nuclear activity in galaxies may be intimately linked via the common triggering mechanism of mergers and...

PublicationTurbulent Gas in Lensed Planck-selected Starbursts at z ∼ 1-3.5
Dusty star-forming galaxies at high redshift (1 < z < 3) represent the most intense star-forming regions in the universe. Key aspects to these processes are the...

TalkWitnessing the Formation of Massive, Distant Galaxies in the (Sub)Millimeter Regime
In order to understand galaxy formation it is crucial to obtain sensitive observations of the emission of dust and molecular gas both of which constrain the on...
