GASP XXIII: A Jellyfish Galaxy as an Astrophysical Laboratory of the Baryonic Cycle [PDF]

open access: yesThe 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).

The slow death of red galaxies [PDF]

open access: yesNature, 2015
This a nearly final draft of a News and Views appeared on Nature in May 2015. It also summarises the content of the talk "Shutdown and downsizing" that I presented at the EWASS meeting "How galaxies live and die: the onset and end of star formation across cosmic time" (Athens, Greece, 6th July 2016)

Exploring galaxies-gravitational waves cross-correlations as an astrophysical probe [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
Gravitational waves astronomy has opened a new opportunity to study the Universe. Full exploitation of this window can especially be provided by combining data coming from gravitational waves experiments with luminous tracers of the Large Scale Structure, like galaxies.

Applications of the IGIMF-theory to the astrophysics of galaxies

open access: yes, 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 ...

Spiral galaxies as enantiomers: Chirality, an underlying feature in chemistry and astrophysics [PDF]

open access: yesChirality, 2005
AbstractSpiral galaxies are axisymmetric objects showing 2D chirality when projected onto a plane. Features in common with tetrahedral molecules are pointed out, in particular the existence of a preferred chiral modality for genetic galaxies as in amino acids and sugars. Environmental effects can influence the intrinsic chirality of originally isolated

High Energy Neutrino Emission from Astrophysical Jets in the Galaxy [PDF]

open access: yesAdvances in High Energy Physics, 2015
We address simulated neutrino emission originated from astrophysical jets of compact objects within the Galaxy. These neutrinos are of high energies (Eνof the order up to a few TeV) and for their observation specialized instruments are in operation, both on Earth and in orbit.

Galaxy Winds in the Age of Hyperdimensional Astrophysics

open access: yes, 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

Groups of galaxies in the Center for Astrophysics redshift survey

open access: yesThe Astrophysical Journal, 1989
By applying the Huchra and Geller (1982) objective group identification algorithm to the Center for Astrophysics' redshift survey, a catalog of 128 groups with three or more members is extracted, and 92 of these are used as a statistical sample. A comparison of the distribution of group centers with the distribution of all galaxies in the survey ...

The astrophysical consequences of intervening galaxy gas on fast radio bursts [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2017
We adopt and analyze results on the incidence and physical properties of damped Ly$ $ 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 ...
