Neutral Hydrogen Observations of Low Surface Brightness Galaxies around M101 and NGC 5485
Ananthan Karunakaran, Kristine Spekkens, Paul Bennet +3
We present atomic hydrogen (HI) observations using the Robert C. Byrd Green Bank Telescope along the lines-of-sight to 27 low surface brightness (LSB) dwarf galaxy candidates disco…
CHANG-ES XV: Large-scale magnetic field reversals in the radio halo of NGC 4631
Silvia Carolina Mora-Partiarroyo, Marita Krause, Aritra Basu +13
NGC 4631 is an interacting galaxy which exhibits one of the largest gaseous halos observed among edge-on galaxies. We aim to examine the synchrotron and polarization properties of…
CHANG-ES XIV: Cosmic-ray propagation and magnetic field strengths in the radio halo of NGC 4631
Silvia Carolina Mora-Partiarroyo, Marita Krause, Aritra Basu +13
NGC 4631 is an interacting galaxy that exhibits one of the largest, gaseous halos observed among edge-on galaxies. We aim to examine the synchrotron and cosmic-ray propagation prop…
The Intrinsic Scatter of the Radial Acceleration Relation
Connor Stone, Stephane Courteau
We present a detailed Monte Carlo model of observational errors in observed galaxy scaling relations to recover the intrinsic (cosmic) scatter driven by galaxy formation and evolut…
On The Role of Supermassive Black Holes in Quenching Star Formation in Local Central Galaxies
Nikhil Arora, Matteo Fossati, Fabio Fontanot +2
In this work, we analyze the role of AGN feedback in quenching star formation for massive, central galaxies in the local Universe. In particular, we compare the prediction of two s…
CHANG-ES XVI: An in-depth view of the cosmic-ray transport in the edge-on spiral galaxies NGC 891 and NGC 4565
Philip Schmidt, Marita Krause, Volker Heesen +8
Cosmic-ray electrons (CREs) originating from the star-forming discs of spiral galaxies frequently form extended radio haloes that are best observable in edge-on galaxies. For the p…
CHANG-ES XIX: Galaxy NGC 4013 -- a diffusion-dominated radio halo with plane-parallel disk and vertical halo magnetic fields
Y. Stein, R. -J. Dettmar, M. Wezgowiec +9
Using the Continuum HAloes in Nearby Galaxies - an EVLA Survey (CHANG-ES) radio continuum data from the Karl G. Jansky Very Large Array (VLA) in two frequency bands (C-band, L-band…
CHANG-ES XVII: H-alpha Imaging of Nearby Edge-on Galaxies, New SFRs, and an Extreme Star Formation Region -- Data Release 2
Carlos J. Vargas, Rene Walterbos, Richard Rand +5
We present new narrow-band H-alpha imaging for 24 nearby edge-on galaxies in the CHANG-ES survey. We use the images in conjunction with WISE 22 micron imaging of the sample to esti…
The Assembly of the Virgo Cluster, Traced by its Galaxy Halos
James E. Taylor, Jihye Shin, Nathalie N. -Q. Ouellette +1
Kinematic studies have produced accurate measurements of the total dark matter mass and mean dark matter density within the optical extent of galaxies, for large samples of objects…
Pipe3D Stellar and Gaseous Velocity Dispersions for CALIFA Galaxies
Colleen Gilhuly, Stéphane Courteau, Sebastian F. Sánchez
We present tables of velocity dispersions derived from CALIFA V1200 datacubes using Pipe3D. Four different dispersions are extracted from emission (ionized gas) or absorption (stel…
The M101 Satellite Luminosity Function and the Halo to Halo Scatter Among Local Volume Hosts
P. Bennet, D. J. Sand, D. Crnojević +4
We have obtained deep Hubble Space Telescope (HST) imaging of 19 dwarf galaxy candidates in the vicinity of M101. Advanced Camera for Surveys HST photometry for 2 of these objects…
Evolving Galactic Dynamos and Fits to the Reversing Rotation Measures in the Halo of NGC 4631
Alex Woodfinden, Richard Henriksen, Judith Irwin +1
Rotation measure (RM) synthesis maps of NGC 4631 show remarkable sign reversals with distance from the minor axis in the northern halo of the galaxy on kpc scales. To explain this…
CHANG-ES XX. High Resolution Radio Continuum Images of Edge-on Galaxies and their AGNs -- Data Release 3
Judith Irwin, Theresa Wiegert, Alison Merritt +17
The CHANG-ES galaxy sample consists of 35 nearby edge-on galaxies that have been observed using the VLA at 1.6 GHz and 6.0 GHz. Here we present the 3rd data release of our sample,…
GalactICS with Gas
N. Deg, L. M. Widrow, T. Randriamampandry +1
We present a new version of the GalactICS code that can generate self-consistent equilibrium galaxy models with a two-component stellar disc and a gas disc as well as a centrally-c…
Eigenfunctions of Galactic Phase Space Spirals from Dynamic Mode Decomposition
Keir Darling, Lawrence M. Widrow
We investigate the spatiotemporal structure of simulations of the homogeneous slab and isothermal plane models for the vertical motion in the Galactic disc. We use Dynamic Mode Dec…
CHANG-ES: XVIII---The CHANG-ES Survey and Selected Results
Judith Irwin, Ancor Damas-Segovia, Marita Krause +8
The CHANG-ES (Continuum Halos in Nearby Galaxies) survey of 35 nearby edge-on galaxies is revealing new and sometimes unexpected and startling results in their radio continuum emis…
A `Numbers' Approach to Astronomical Correlations I: Introduction and Application to galaxy Scaling Relations
R. N. Henriksen, J. A. Irwin
We propose a new systematic method of studying correlations between parameters that describe an astronomical (or any) physical system. We recall that behind Dimensionless scaling l…
CHANG-ES XIII: Transport processes and the magnetic fields of NGC 4666 - indication of a reversing disk magnetic field
