IN-N-OUT: THE GAS CYCLE FROM DWARFS TO SPIRAL GALAXIES [PDF]
, 2015 We examine the scalings of galactic outflows with halo mass across a suite of 20 high-resolution cosmological zoom galaxy simulations covering halo masses in the range .

Dawes Review 4: Spiral Structures in Disc Galaxies [PDF]
Publications Astronomical Society of Australia, 2014 The majority of astrophysics involves the study of spiral galaxies, and stars and planets within them, but how spiral arms in galaxies form and evolve is still a fundamental problem. Major progress in this field was made primarily in the 1960s, and early

NUMERICAL MODELLING OF GAS DYNAMIC STRUCTURES IN SPIRAL GALAXIES
Odessa Astronomical Publications, 2013 Observations show that in the global morphology of spiral galaxies appear and form multi-scale features that are embedded in a complex complete picture of the galaxy.

The Origin and Evolution of Giant Radio Galaxies
Frontiers in Astronomy and Space Sciences, 2022 Giant radio galaxies are arguably the least understood of jetted active galactic nuclei (AGN). We propose that radio galaxies are the product of large mergers that do not involve radio galaxies or radio quasars, such as in merging spiral galaxies, while ...

Dependence of stellar substructures in M31 type galaxy on satellite morphology in galaxy mergers [PDF]
Serbian Astronomical Journal, 2022 Stellar streams and shells are observed in halos of spiral galaxies. In this paper, we investigated the formation of these structures due to mergers between the host spiral galaxy and its dwarf satellite galaxies.

MAGNETIC FIELDS IN A SAMPLE OF NEARBY SPIRAL GALAXIES [PDF]
, 2014 Both observations and modeling of magnetic fields in the diffuse interstellar gas of spiral galaxies are well developed, but the theory has been confronted with observations for only a handful of individual galaxies.

Galaxies, 2018 Spiral galaxies are spinning, internally densified objects. The Virial Theorem explains galactic rotation curves via its linkage of the rotation rate to the gravitational self-potential (Ug) and the moment of inertia of oblate spheroids.

THE BLACK HOLE MASS FUNCTION DERIVED FROM LOCAL SPIRAL GALAXIES [PDF]
, 2014 We present our determination of the nuclear supermassive black hole (SMBH) mass function for spiral galaxies in the local universe, established from a volume-limited sample consisting of a statistically complete collection of the brightest spiral ...

GASP XXIX-unwinding the arms of spiral galaxies via ram-pressure stripping [PDF]
, 2020 We present the first study of the effect of ram pressure ‘unwinding’ the spiral arms of cluster galaxies. We study 11 ram-pressure stripped galaxies from GASP (GAs Stripping Phenomena in galaxies) in which, in addition to more commonly observed ...
