Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers
The Astrophysical Journal, 2023 Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures.

Be it therefore resolved: cosmological simulations of dwarf galaxies with 30 solar mass resolution [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We study a suite of extremely high-resolution cosmological Feedback in Realistic Environments simulations of dwarf galaxies ($M_{\rm halo} \lesssim 10^{10}\rm \, M_{\odot }$), run to z = 0 with $30\, \mathrm{M}_{\odot }$ resolution, sufficient (for the

Satellites and haloes of dwarf galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 We study the abundance of satellite galaxies as a function of primary stellar mass using the SDSS/DR7 spectroscopic catalogue. In contrast with previous studies, which focussed mainly on bright primaries, our central galaxies span a wide range of stellar mass, 10^7.5 < M_*^pri/M_sun < 10^11, from dwarfs to central cluster galaxies.

The Effect of Dwarf Galaxies on the Tidal Tails of Globular Clusters [PDF]
, 2021 The tidal tails of globular clusters have been shown to be sensitive to the external tidal field. We investigate how Galactic globular clusters with observed tails are affected by satellite dwarf galaxies by simulating tails in galaxy models with and without dwarf galaxies.

AGN-Driven Outflows in Dwarf Galaxies [PDF]
Astrophysical Journal, 2019 We present spatially resolved kinematic measurements of active galactic nucleus (AGN)-driven outflows in dwarf galaxies in the stellar mass range ∼6 × 108–9 × 109 M⊙, selected from SDSS DR7 and DR8 and followed-up with Keck/LRIS spectroscopy.

The Interstellar Medium of Dwarf Galaxies [PDF]
Galaxies, 2022 Dwarf galaxies are by far the most numerous galaxies in the Universe, showing properties that are quite different from those of their larger and more luminous cousins. This review focuses on the physical and chemical properties of the interstellar medium of those dwarfs that are known to host significant amounts of gas and dust. The neutral and ionized

Dark influences: imprints of dark satellites on dwarf galaxies [PDF]
, 2014 In the context of the current $\Lambda$CDM cosmological model small dark matter haloes are abundant and satellites of dwarf galaxies are expected to be predominantly dark.

Thin disk of co-rotating dwarfs: a fingerprint of dissipative (mirror) dark matter? [PDF]
, 2013 Recent observations indicate that about half of the dwarf satellite galaxies around M31 orbit in a thin plane approximately aligned with the Milky Way. It has been argued that this observation along with several other features can be explained if these ...

Neutron-capture elements in dwarf galaxies [PDF]
Astronomy & Astrophysics, 2019 Context. We present a large homogeneous set of stellar parameters and abundances across a broad range of metallicities, involving 13 classical dwarf spheroidal (dSph) and ultra-faint dSph (UFD) galaxies. In total, this study includes 380 stars in Fornax,

The evolution of dwarf galaxies [PDF]
Astrophysics and Space Science, 1988 We propose an evolutionary model for dwarf galaxies in Which initially metal-poor gas-rich dwarf irregular (dI) galaxies evolve through bursting Blue Compact Dwarf(BCD) stages and eventually fade from the BCD phase to become dwarf ellipticals (dE). During the bursting phase the surface brightness of the galaxy increases rapidly due to enhanced OB star ...
