Balmer filaments in Tycho's supernova remnant: an interplay between cosmic-ray and broad-neutral precursors
Sladjana Knežević, Ronald Läsker, Glenn van de Ven +8
We present H spectroscopic observations and detailed modelling of the Balmer filaments in the supernova remnant Tycho. We used Galaxy H Fabry-Pérot Spectrometer on the Willia…
Balmer-dominated shocks in Tycho's SNR: omnipresence of CRs
Sladjana Knežević, Ronald Läsker, Glenn van de Ven +8
We present wide-field, spatially and highly resolved spectroscopic observations of Balmer filaments in the northeastern rim of Tycho's supernova remnant in order to investigate the…
Circumnuclear Structures in Megamaser Host Galaxies
Patryk Pjanka, Jenny E. Greene, Anil C. Seth +4
Using HST, we identify circumnuclear (- pc scale) structures in nine new HO megamaser host galaxies to understand the flow of matter from kpc-scale galactic structure…
H Imaging spectroscopy of Balmer-dominated shocks in Tycho's supernova remnant
Sladjana Knežević, Ronald Läsker, Glenn van de Ven +4
We present Fabry-Pérot interferometric observations of the narrow H component in the shock front of the historical supernova remnant Tycho (SN 1572). Using GHFaS (Galaxy H…
The Black Hole - Bulge Mass Relation in Megamaser Host Galaxies
Ronald Läsker, Jenny E. Greene, Anil Seth +4
We present HST images for nine megamaser disk galaxies with the primary goal of studying photometric BH-galaxy scaling relations. The megamaser disks provide the highest-precision…
Discovery of an ultra-diffuse galaxy in the Pisces-Perseus supercluster
David Martinez-Delgado, Ronald Laesker, Margarita Sharina +16
We report the discovery of DGSAT I, an ultra-diffuse, quenched galaxy located 10.4 degrees in projection from the Andromeda galaxy (M31). This low-surface brightness galaxy (mu_V =…
The massive dark halo of the compact, early-type galaxy NGC 1281
Akın Yıldırım, Remco van den Bosch, Glenn van de Ven +7
We investigate the compact, early-type galaxy NGC 1281 with integral field unit observations to map the stellar LOSVD out to 5 effective radii and construct orbit-based dynamical m…
Circumnuclear Molecular Gas in Megamaser Disk Galaxies NGC 4388 and NGC 1194
Jenny E. Greene, Anil Seth, Mariya Lyubenova +3
We explore the warm molecular and ionized gas in the centers of two megamaser disk galaxies using K-band spectroscopy. Our ultimate goal is to determine how gas is funneled onto th…
Supermassive Black Holes and Their Host Galaxies - II. The correlation with near-infrared luminosity revisited
Ronald Läsker, Laura Ferrarese, Glenn van de Ven +1
We present an investigation of the scaling relations between Supermassive Black Hole (SMBH) masses (Mbh), and their host galaxies' K-band bulge (Lbul) and total (Ltot) luminosities…
Supermassive Black Holes and Their Host Galaxies - I. Bulge luminosities from dedicated near-infrared data
Ronald Läsker, Laura Ferrarese, Glenn van de Ven
In an effort to secure, refine and supplement the relation between central Supermassive Black Hole masses (Mbh), and the bulge luminosities of their host galaxies, (Lbul), we obtai…
Bottom-heavy initial mass function in a nearby compact L*-galaxy
Ronald Läsker, Remco C. E. van den Bosch, Glenn van de Ven +4
We present orbit-based dynamical models and stellar population analysis of galaxy SDSS J151741.75-004217.6, a low-redshift (z=0.116) early-type galaxy (ETG) which, for its moderate…
