Predicting the broad lines polarization emitted by supermassive binary black holes
Đ. Savić, F. Marin, L. Č. Popović
Some Type-1 active galactic nuclei (AGNs) are showing extremely asymmetric Balmer lines with the broad peak redshifted or blueshifted by thousands of km/s. These AGNs may be good c…
The Next Generation Virgo Cluster Survey. XXIII. Fundamentals of nuclear star clusters over seven decades in galaxy mass
R. Sánchez-Janssen, P. Côté, L. Ferrarese +25
Using deep, high resolution optical imaging from the Next Generation Virgo Cluster Survey we study the properties of nuclear star clusters (NSCs) in a sample of nearly 400 quiescen…
The ultra-diffuse galaxy NGC 1052-DF2 with MUSE: I. Kinematics of the stellar body
Eric Emsellem, Remco F. J. van der Burg, Jeremy Fensch +14
The so-called ultra-diffuse galaxy NGC~1052-DF2 was announced to be a galaxy lacking dark matter based on a spectroscopic study of its constituent globular clusters. Here we presen…
Peak star formation efficiency and no missing baryons in massive spirals
Lorenzo Posti, Filippo Fraternali, Antonino Marasco
It is commonly believed that galaxies use, throughout the Hubble time, a very small fraction of the baryons associated to their dark matter halos to form stars. This so-called low…
The signatures of the resonances of a large Galactic bar in local velocity space
Giacomo Monari, Benoit Famaey, Arnaud Siebert +2
The second data release of the Gaia mission has revealed a very rich structure in local velocity space. In terms of in-plane motions, this rich structure is also seen as multiple r…
Angular momentum regulates HI gas content and HI central hole size in the discs of spirals
Chandrashekar Murugeshan, Virginia Kilborn, Danail Obreschkow +4
The neutral atomic hydrogen (HI) content of spiral galaxies has been observed to vary with environment, with more HI-deficient spirals residing in high density environments. This c…
The number of dwarf satellites of disk galaxies versus their bulge mass in the standard model of cosmology
B. Javanmardi, M. Raouf, H. G. Khosroshahi +3
There is a correlation between bulge mass of the three main galaxies of the Local Group (LG), i.e. M31, Milky Way (MW), and M33, and the number of their dwarf spheroidal galaxies.…
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…
Dark matter-baryon scaling relations from Einasto halo fits to SPARC galaxy rotation curves
Amir Ghari, Benoit Famaey, Chervin Laporte +1
Dark matter-baryon scaling relations in galaxies are important in order to constrain galaxy formation models. Here, we provide a modern quantitative assessment of those relations,…
Reliable mass calculation in spherical gravitating systems
Foivos I. Diakogiannis, Geraint F. Lewis, Rodrigo A. Ibata +3
We present an innovative approach to the methodology of dynamical modelling, allowing practical reconstruction of the underlying dark matter mass without assuming both the density…
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…
Mirach's Goblin: Discovery of a dwarf spheroidal galaxy behind the Andromeda galaxy
David Martinez-Delgado, Eva K. Grebel, Behnam Javanmardi +9
It is of broad interest for galaxy formation theory to carry out a full inventory of the numbers and properties of dwarf galaxies in the Local Volume, both satellites and isolated…
The outer halo globular cluster system of M31 - III. Relationship to the stellar halo
Dougal Mackey, Annette Ferguson, Avon Huxor +10
We utilise the final catalogue from the Pan-Andromeda Archaeological Survey to investigate the links between the globular cluster system and field halo in M31 at projected radii $R…
A-type stars in the Canada-France Imaging Survey II. Tracing the height of the disc at large distances with Blue Stragglers
Guillaume F. Thomas, Chervin F. P. Laporte, Alan W. McConnachie +7
We present the kinematics of Blue Straggler (BS) stars identified in the Canada-France-Imaging-Survey (CFIS), covering 4000 deg on the sky in the -band. The BS sample, chara…
Local disc model in view of Gaia DR1 and RAVE data
K. Sysoliatina, A. Just, I. Koutsouridou +8
We test the performance of the semi-analytic self-consistent Just-Jahreiß disc model (JJ model) with the astrometric data from the Tycho-Gaia Astrometric Solution (TGAS) sub-catalo…
The Dust-Selected Molecular Clouds in the Northeast Region of the Small Magellanic Cloud
Tatsuya Takekoshi, Tetsuhiro Minamidani, Shinya Komugi +19
We present a high-sensitivity () continuum observation in a 343 arcmin area of the northeast region in the Small Magellanic Cloud at a wavelength…
A-type stars in the Canada-France Imaging Survey I. The stellar halo of the Milky Way traced to large radius by blue horizontal branch stars
Guillaume F. Thomas, Alan W. McConnachie, Rodrigo A. Ibata +14
We present the stellar density profile of the outer halo of the Galaxy traced over a range of Galactocentric radii from kpc by blue horizontal branch (BHB) stars…
A new dynamically self-consistent version of the Besançon Galaxy Model
Olivier Bienaymé, Jérome Leca, Annie C. Robin
Context. Dynamically self-consistent galactic models are necessary for analysing and interpreting star counts, stellar density distributions, and stellar kinematics in order to und…
Early- and late-stage mergers among main sequence and starburst galaxies at 0.2<z<2
A. Cibinel, E. Daddi, M. T. Sargent +12
We investigate the fraction of close pairs and morphologically identified mergers on and above the star-forming main sequence (MS) at 0.22.0. The novelty of our work li…
