Cosmic ray feedback in galaxies and galaxy clusters: A pedagogical introduction and a topical review of the acceleration, transport, observables, and dynamical impact of cosmic rays. [PDF]
Astron Astrophys Rev, 2023 Understanding the physical mechanisms that control galaxy formation is a fundamental challenge in contemporary astrophysics. Recent advances in the field of astrophysical feedback strongly suggest that cosmic rays (CRs) may be crucially important for our

Hidden Hearts of Neutrino Active Galaxies [PDF]
Astrophysical Journal Letters, 2022 Recent multimessenger studies have provided evidence for high-energy neutrino sources that are opaque to GeV–TeV gamma rays. We present model-independent studies on the connection between neutrinos and gamma rays in the active galaxy NGC 1068, and find ...

Lopsided Galaxies, Weak Interactions, and Boosting the Star Formation Rate [PDF]
, 2000 To investigate the link between weak tidal interactions in disk galaxies and the boosting of their recent star formation, we obtain images and spatially integrated spectra (3615 Å ≤ λ ≤ 5315 Å) for 40 late-type spiral galaxies (Sab-Sbc) with varying ...

Annual Review of Astronomy and Astrophysics, 2021 Spirals in galaxies have long been thought to be caused by gravitational instability in the stellar component of the disk, but discerning the precise mechanism had proved elusive.

Velocity-dependent self-interacting dark matter from groups and clusters of galaxies [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We probe the self-interactions of dark matter with relaxed galaxy groups and clusters using observational data from strong and weak lensing and stellar kinematics.

Dark matter–radiation interactions : the structure of Milky Way satellite galaxies. [PDF]
, 2015 In the thermal dark matter (DM) paradigm, primordial interactions between DM and Standard Model particles are responsible for the observed DM relic density. In Bhm et al. (2014), we showed that weak-strength interactions between DM and radiation (photons

Galaxy And Mass Assembly (GAMA): the effect of close interactions on star formation in galaxies [PDF]
, 2015 The modification of star formation (SF) in galaxy interactions is a complex process, with SF observed to be both enhanced in major mergers and suppressed in minor pair interactions.

DWARF GALAXIES OF THE LOCAL GROUP [PDF]
, 1998 ▪ Abstract The Local Group dwarf galaxies offer a unique window to the detailed properties of the most common type of galaxy in the Universe. In this review, I update the census of Local Group dwarfs based on the most recent distance and radial velocity ...

Interacting galaxies on FIRE-2: the connection between enhanced star formation and interstellar gas content [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present a comprehensive suite of high-resolution (parsec-scale), idealised (non-cosmological) galaxy merger simulations (24 runs, stellar mass ratio ~2.5:1) to investigate the connection between interaction-induced star formation and the evolution of ...
