On the Tully–Fisher Relation for Active Galaxies. I. Evidence of Larger Scatter

The Astrophysical Journal
We present an investigation of the Tully–Fisher (TF) relation solely for galaxies hosting an active galactic nucleus (AGN). Using 22 galaxies with primary, z -independent distances, we find that active galaxies exhibit significantly larger scatter about ...

Cis–Trans Rotational Isomerism of Formic Acid, Sulfur, and Selenium Analogues and Their Dimers: Chemical Kinetics Under Interstellar Conditions

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT We present chemical kinetic rate constants for the cis to trans isomerisation or rotamerization of monomeric seleno‐, thio‐, and formic acids and that of three of their dimeric species, based on variational transition state theory and multidimensional tunneling calculations in the gas‐phase, from 10 K to 300 K. These provide, firstly, reliable

Active galaxies in the local Universe: Feedback, variability, and triggering

, 2017
This thesis investigates the coevolution of galaxies and their supermassive black holes. We use spatially resolved spectroscopic data to search for evidence of AGN feedback and triggering.

The ATLAS(3D) project - XXV. Two-dimensional kinematic analysis of simulated galaxies and the cosmological origin of fast and slow rotators [PDF]

, 2014
We present a detailed two-dimensional stellar dynamical analysis of as ample of 44 cosmological hydrodynamical simulations of individual central galaxies with stellar masses of 2 x 1010Msun ∼≤ Mstar ∼≤ 6x 1011Msun.

HD‐DRUM Rhythmic Training in Huntington's Disease: Feasibility, Motor, and Brain Microstructural Pilot Signals

Movement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Rhythmic cuing may benefit motor functions in Huntington's disease (HD) by compensating for the loss of predictive timing associated with basal ganglia degeneration. To our knowledge no remote rhythmic training application has been developed or evaluated that seeks to improve function in HD.

The nature and origin of disky elliptical galaxies [PDF]

, 2002
The observational trend that disky elliptical galaxies exhibit younger luminosity- weighted ages than boxy ellipticals is investigated. The presence of a possible young stellar disk embedded in these galaxies is explored by comparing kinematics derived ...

The Search for Very High Energy γ-rays from Misaligned AGN [PDF]

, 2013
The aim of this work is to study the potential for emission at very high energies (100 GeV) by misaligned active galactic nuclei (AGN) and the future prospects for observations of these objects with the next generation imaging atmospheric Cherenkov ...
