CHANG-ES VI: Probing Supernova Energy Deposition in Spiral Galaxies Through Multi-Wavelength Relationships

Jiang-Tao Li, Rainer Beck, Ralf-Jurgen Dettmar +13

How a galaxy regulates its SNe energy into different interstellar/circumgalactic medium components strongly affects galaxy evolution. Based on the JVLA D-configuration C- (6 GHz) a…

The warm ionized gas in CALIFA early-type galaxies: 2D emission-line patterns and kinematics for 32 galaxies

J. M. Gomes, P. Papaderos, C. Kehrig +23

The morphological, spectroscopic and kinematical properties of the warm interstellar medium (wim) in early-type galaxies (ETGs) hold key observational constraints to nuclear activi…

Spectroscopic aperture biases in inside-out evolving early-type galaxies from CALIFA

J. M. Gomes, P. Papaderos, J. M. Vílchez +21

Integral field spectroscopy studies based on CALIFA data have recently revealed the presence of ongoing low-level star formation (SF) in the periphery of ~10% of local early-type g…

Spiral-like star-forming patterns in CALIFA early-type galaxies

J. M. Gomes, P. Papaderos, J. M. Vílchez +21

Based on a combined analysis of SDSS imaging and CALIFA integral field spectroscopy data, we report on the detection of faint (24 < μ mag/arcsec < 26) star-forming spiral-a…

Cold-gas outflows in typical low-redshift galaxies are driven by star formation, not AGN

Marc Sarzi, Sugata Kaviraj, Boris Nedelchev +4

Energetic feedback from active galactic nuclei (AGN) is an important ingredient for regulating the star-formation history of galaxies in models of galaxy formation, which makes it…

Wide-field LOFAR imaging of the field around the double-double radio galaxy B1834+620: A fresh view on a restarted AGN and doubeltjes

E. Orrú, S. van Velzen, R. F. Pizzo +8

The existence of double-double radio galaxies (DDRGs) is evidence for recurrent jet activity in AGN, as expected from standard accretion models. A detailed study of these rare sour…
