The Many Routes to AGN Feedback [PDF]

, 2017
The energy released by Active Galactic Nuclei (AGN) in the form of radiation, winds, or radio plasma jets, is known to impact on the surrounding interstellar medium. The result of these processes, known as AGN (negative) feedback, is suggested to prevent

Tracing the Mass-Assembly History of Galaxies with Deep Surveys

, 2007
We use the optical and near-infrared galaxy samples from the Munich Near-Infrared Cluster Survey (MUNICS), the FORS Deep Field (FDF) and GOODS-S to probe the stellar mass assembly history of field galaxies out to z ~ 5.

Tracing Ghost Cavities with Low Frequency Radio Observations [PDF]

, 2006
We present X-ray and multi-frequency radio observations of the central radio sources in several X-ray cavity systems. We show that targeted radio observations are key to determining if the lobes are being actively fed by the central AGN.

Stability of disk-like galaxies--Part I: Stability via reduction [PDF]

, 2006
We prove the existence and stability of flat steady states of the Vlasov-Poisson system, which in astrophysics are used as models of disk-like galaxies.

Giant radio galaxies as probes of the ambient WHIM in the era of the SKA

, 2015
The missing baryons are usually thought to reside in galaxy filaments as warm-hot intergalactic medium (WHIM). From previous studies, giant radio galaxies are usually associated with galaxy groups, which normally trace the WHIM.

Are truncated stellar disks linked to the molecular gas density? [PDF]

, 2007
We know that the slope of the radial, stellar light distribution in galaxies is well described by an exponential decline and this distribution is often truncated at a break radius ($R_{br}$).
