CHANG-ES XII: A LOFAR and VLA view of the edge-on star-forming galaxy NGC 3556
A. Miskolczi, V. Heesen, C. Horellou +11
Low-frequency radio continuum studies of star-forming edge-on galaxies can help to further understand how cosmic-ray electrons (CRe) propagate through the interstellar medium into…
Systematically Measuring Ultra Diffuse Galaxies (SMUDGes). I. Survey Description and First Results in the Coma Galaxy Cluster and Environs
Dennis Zaritsky, Richard Donnerstein, Arjun Dey +6
We present a homogeneous catalog of 275 large (effective radius 5.3 arcsec) ultra-diffuse galaxy (UDG) candidates lying within an 290 square degree region surro…
The large-scale structure of the halo of the Andromeda galaxy II. Hierarchical structure in the Pan-Andromeda Archaeological Survey
Alan W. McConnachie, Rodrigo Ibata, Nicolas Martin +29
The Pan-Andromeda Archaeological Survey is a survey of square degrees centered on the Andromeda (M31) and Triangulum (M33) galaxies that has provided the most extensive pano…
Unique Tracks Drive the Scatter of the Spatially-Resolved Star Formation Main Sequence
Christine Hall, Stephane Courteau, Thomas Jarrett +4
The scatter of the spatially resolved star formation main sequence (SFMS) is investigated in order to reveal signatures about the processes of galaxy formation and evolution. We ha…
Evidence for Ultra-Diffuse Galaxy `Formation' Through Galaxy Interactions
Paul Bennet, David J. Sand, Dennis Zaritsky +3
We report the discovery of two ultra-diffuse galaxies (UDGs) which show clear evidence for association with tidal material and interaction with a larger galaxy halo, found during a…
Can Stellar Discs in a Cosmological Setting Avoid Forming Strong Bars?
Jacob S. Bauer, Lawrence M. Widrow
We investigate the connection between the vertical structure of stellar discs and the formation of bars using high-resolution simulations of galaxies in isolation and in the cosmol…
Simulating non-axisymmetric flows in disc galaxies
T. H. Randriamampandry, N. Deg, C. Carignan +1
We present a two-step method to simulate and study non-circular motions in strongly barred galaxies. The first step is to constrain the initial parameters using a Bayesian analysis…
Emergence of the Gaia Phase Space Spirals from Bending Waves
Keir Darling, Lawrence M. Widrow
We discuss the physical mechanism by which pure vertical bending waves in a stellar disc evolve to form phase space spirals similar to those discovered by Antoja et al. ( arXiv:180…
Non-parametric decompositions of disk galaxies in SG using DiskFit
Colin Lewis, Kristine Spekkens
We present photometric models of 532 disk galaxies in 3.6μm images from the Spitzer Survey of Stellar Structure in Galaxies (SG) using the non-parametric DiskFit algorithm. We…
Formation of LISA Black Hole Binaries in Merging Dwarf Galaxies: the Imprint of Dark Matter
Tomas Tamfal, Pedro R. Capelo, Stelios Kazantzidis +4
Theoretical models for the expected merger rates of intermediate-mass black holes (IMBHs) are vital for planned gravitational-wave detection experiments such as the Laser Interfero…
Bending Waves in the Milky Way's disc from halo substructure
Matthew H. Chequers, Lawrence M. Widrow, Keir Darling
We use -body simulations to investigate the excitation of bending waves in a Milky Way-like disc-bulge-halo system. The dark matter halo consists of a smooth component and a pop…
A Deeper Look at the New Milky Way Satellites: Sagittarius II, Reticulum II, Phoenix II, and Tucana III
Burçin Mutlu-Pakdil, David J. Sand, Jeffrey L. Carlin +6
We present deep Magellan/Megacam stellar photometry of four recently discovered faint Milky Way satellites: Sagittarius II (Sgr II), Reticulum II (Ret II), Phoenix II (Phe II), and…
An Extensive Photometric Catalog of CALIFA Galaxies
Colleen Gilhuly, Stéphane Courteau
We present an extensive compendium of photometrically-determined structural properties for all CALIFA galaxies in the Third Data Release (DR3). We exploit Sloan Digital Sky Survey…
CHANG-ES XI: Circular Polarization in the Cores of Nearby Galaxies
Judith A Irwin, Richard N. Henriksen, Marek Wezgowiec +18
We detect 5 galaxies in the CHANG-ES (Continuum Halos in Nearby Galaxies -- an EVLA Survey) sample that show circular polarization (CP) at L-band in our high resolution data sets.…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE).I. Introduction to the Survey
A. Boselli, M. Fossati, L. Ferrarese +56
The Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) is a blind narrow-band Halpha+[NII] imaging survey carried out with MegaCam at the Canada-France-Hawaii Telesc…
Exact axially symmetric galactic dynamos
R. N. Henriksen, A. Woodfinden, J. A. Irwin
We give a selection of exact dynamos in axial symmetry on a galactic scale. These include some steady examples, at least one of which is wholly analytic in terms of simple function…
Radio haloes in nearby galaxies modelled with 1D cosmic-ray transport using SPINNAKER
V. Heesen, M. Krause, R. Beck +10
We present radio continuum maps of 12 nearby (), edge-on (), late-type spiral galaxies mostly at and 5 GHz, observed with the Australia Te…
Disc-Halo Interactions in ΛCDM
Jacob S. Bauer, Lawrence M. Widrow, Denis Erkal
We present a new method for embedding a stellar disc in a cosmological dark matter halo and provide a worked example from a ΛCDM zoom-in simulation. The disc is inserted into the h…
CHANG-ES X: Spatially-resolved Separation of Thermal Contribution from Radio Continuum Emission in Edge-on Galaxies
Carlos J. Vargas, Silvia Carolina Mora-Partiarroyo, Philip Schmidt +12
We analyze the application of star formation rate (SFR) calibrations using H and 22 micron infrared imaging data in predicting the thermal radio component for a test sample of 3…
