Lorentz-violating signatures in quasi-periodic oscillations from a magnetised Kalb-Ramond black hole
Luiz F. G. Rodrigues, Francisco S. N. Lobo, Manuel E. Rodrigues
We investigate the dynamics of charged particles around a Schwarzschild-like black hole sourced by a Kalb-Ramond field and immersed in a uniform external magnetic field. The Kalb-R…
Radio Continuum Emission from Evolving Star-Forming Galaxies -- I. Correlations Involving the Total Synchrotron Luminosity
Sukanta Ghosh, Luke Chamandy, Charles Jose +3
Synchrotron radiation dominates the continuum emission of star-forming galaxies in the frequency range from a few to about . We model the total synchrotron…
Understanding the radio luminosity function of star-forming galaxies and its cosmological evolution
Charles Jose, Luke Chamandy, Anvar Shukurov +3
We explore the redshift evolution of the radio luminosity function (RLF) of star-forming galaxies using GALFORM, a semi-analytic model of galaxy formation and a dynamo model of the…
Steady states of the Parker instability
Devika Tharakkal, Anvar Shukurov, Frederick A. Gent +3
We study the linear properties, nonlinear saturation and a steady, strongly nonlinear state of the Parker instability in galaxies. We consider magnetic buoyancy and its consequence…
Magnetic fields in elliptical galaxies: an observational probe of the fluctuation dynamo action
Amit Seta, Luiz Felippe S. Rodrigues, Christoph Federrath +1
Fluctuation dynamos are thought to play an essential role in magnetized galaxy evolution, saturating within Gyr and thus potentially acting as seeds for large-scale dyna…
The Pencil Code, a modular MPI code for partial differential equations and particles: multipurpose and multiuser-maintained
A. Brandenburg, A. Johansen, P. A. Bourdin +34
The Pencil Code is a highly modular physics-oriented simulation code that can be adapted to a wide range of applications. It is primarily designed to solve partial differential equ…
Redshift estimates for fast radio bursts and implications on intergalactic magnetic fields
Stefan Hackstein, Marcus Brüggen, Franco Vazza +1
Context: Fast Radio Bursts are transient radio pulses from presumably compact stellar sources of extragalactic origin. With new telescopes detecting multiple events per day, statis…
Evolution of galactic magnetic fields
Luiz Felippe S. Rodrigues, Luke Chamandy, Anvar Shukurov +2
We study the cosmic evolution of the magnetic fields of a large sample of spiral galaxies in a cosmologically representative volume by employing a semi-analytic galaxy formation mo…
Fickian and non-Fickian diffusion of cosmic rays
L. F. S. Rodrigues, A. P. Snodin, G. R. Sarson +1
Fluid approximations to cosmic ray (CR) transport are often preferred to kinetic descriptions in studies of the dynamics of the interstellar medium (ISM) of galaxies, because they…
A physical approach to modelling large-scale galactic magnetic fields
Anvar Shukurov, Luiz Felippe S. Rodrigues, Paul J. Bushby +2
A convenient representation of the structure of the large-scale galactic magnetic field is required for the interpretation of polarization data in the sub-mm and radio ranges, in b…
IMAGINE: A comprehensive view of the interstellar medium, Galactic magnetic fields and cosmic rays
Francois Boulanger, Torsten Ensslin, Andrew Fletcher +20
In this white paper we introduce the IMAGINE Consortium and its scientific background, goals and structure. Our purpose is to coordinate and facilitate the efforts of a diverse gro…
Topological signatures of interstellar magnetic fields - I. Betti numbers and persistence diagrams
Irina Makarenko, Anvar Shukurov, Robin Henderson +3
The interstellar medium (ISM) is a magnetised system in which transonic or supersonic turbulence is driven by supernova explosions. This leads to the production of intermittent, fi…
Constraints on galaxy formation models from the galaxy stellar mass function and its evolution
Luiz Felippe S. Rodrigues, Ian Vernon, Richard Bower
We explore the parameter space of the semi-analytic galaxy formation model GALFORM, studying the constraints imposed by measurements of the galaxy stellar mass function (GSMF) and…
The Parker Instability in Disk Galaxies
Luiz Felippe S. Rodrigues, Graeme R. Sarson, Anvar Shukurov +2
We examine the evolution of the Parker instability in galactic disks using 3D numerical simulations. We consider a local Cartesian box section of a galactic disk, where gas, magnet…
Global diffusion of cosmic rays
A. P. Snodin, A. Shukurov, G. R. Sarson +2
The propagation of charged particles, including cosmic rays, in a partially ordered magnetic field is characterized by a diffusion tensor whose components depend on the particle's…
Galactic magnetic fields and hierarchical galaxy formation
Luiz Felippe S. Rodrigues, Anvar Shukurov, Andrew Fletcher +1
A framework is introduced for coupling the evolution of galactic magnetic fields sustained by the mean-field dynamo with the formation and evolution of galaxies in cold dark matter…
The Effect of a Single Supernova Explosion on the Cuspy Density Profile of a Small-Mass Dark Matter Halo
Rafael S. de Souza, Luiz Felippe S. Rodrigues, Emille E. O. Ishida +1
Some observations of galaxies, and in particular dwarf galaxies, indicate a presence of cored density profiles in apparent contradiction with cusp profiles predicted by dark matter…
A large change in the predicted number of small halos due to a small amplitude oscillating inflaton potential
Luiz Felippe S. Rodrigues, Reuven Opher
A smooth inflaton potential is generally assumed when calculating the primordial power spectrum, implicitly assuming that a very small oscillation in the inflaton potential creates…
Random Primordial Magnetic Fields and the Gas Content of Dark Matter Halos
Rafael S. de Souza, Luiz Felippe S. Rodrigues, Reuven Opher
We recently predicted the existence of random primordial magnetic fields (RPMF) in the form of randomly oriented cells with dipole-like structure with a cell size and an aver…
Suppression of small baryonic structures due to a primordial magnetic field
Luiz Felippe S. Rodrigues, Rafael S. de Souza, Reuven Opher
We investigate the impact of the existence of a primordial magnetic field on the filter mass, characterizing the minimum baryonic mass that can form in dark matter (DM) haloes. For…
