The Scales of Gravitational Lensing
Universe, 2016 After exactly a century since the formulation of the general theory of relativity, the phenomenon of gravitational lensing is still an extremely powerful method for investigating in astrophysics and cosmology.

Galaxy Winds in the Age of Hyperdimensional Astrophysics
, 2019 The past decade began with the first light of ALMA and will end at the start of the new era of hyperdimensional astrophysics. Our community-wide movement toward highly multiwavelength and multidimensional datasets has enabled immense progress in each science frontier identified by the 2010 Decadal Survey, particularly with regard to black hole feedback

GASP XXIII: A Jellyfish Galaxy as an Astrophysical Laboratory of the Baryonic Cycle [PDF]
The Astrophysical Journal, 2019 Abstract With MUSE, Chandra, VLA, ALMA, and UVIT data from the GASP program, we study the multiphase baryonic components in a jellyfish galaxy (JW100) with a stellar mass 3.2 × 1011 M ⊙ hosting an active galactic nucleus (AGN).

Cosmology from One Galaxy in a Void?
The Astrophysical Journal LettersUnderstanding galaxy properties may be the key to unlocking some of the most intriguing mysteries of modern cosmology. Recent work relied on machine learning to extract cosmological constraints on Ω _m using only one galaxy.

Applications of the IGIMF-theory to the astrophysics of galaxies
, 2010 The functional form of the galaxy-wide stellar initial mass function is of fundamental importance for understanding galaxies. So far this stellar initial mass function has been assumed to be identical to the IMF observed directly in star clusters. But because stars form predominantly in embedded groups rather than uniformly distributed over the whole ...

The astrophysical consequences of intervening galaxy gas on fast radio bursts [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We adopt and analyze results on the incidence and physical properties of damped Ly$α$ systems (DLAs) to predict the astrophysical impact of gas in galaxies on observations of Fast Radio Bursts (FRBs). Three DLA measures form the basis of this analysis: (i) the HI column density distribution, parameterized as a double power-law; (ii) the incidence of ...

Perfect fluid dark matter: a viability test with galaxy rotation curves
European Physical Journal C: Particles and FieldsThe anomalous rotation curves of galaxies provide compelling evidence for dark matter, yet its fundamental nature and distribution remain key unresolved issues in astrophysics.

HECATEv2: an all-sky galaxy catalogue for multimessenger astrophysics
Monthly Notices of the Royal Astronomical SocietyABSTRACT We present HECATEv2, the second release of the Heraklion Extragalactic Catalogue (HECATE), an all-sky, value-added galaxy catalogue comprising 204 733 galaxies from the Hyper Lyon-Meudon Extragalactic Database (HyperLEDA) with recession velocity $\lt 14\, 000 \, \rm {km\, s^{-1}}$ (D $\lesssim$ 200 Mpc).
