Simulating galaxy formation with black hole driven thermal and kinetic feedback [PDF]
, 2016 The inefficiency of star formation in massive elliptical galaxies is widely believed to be caused by the interactions of an active galactic nucleus (AGN) with the surrounding gas.

A galaxy lacking dark matter [PDF]
Nature, 2018 Studies of galaxy surveys in the context of the cold dark matter paradigm have shown that the mass of the dark matter halo and the total stellar mass are coupled through a function that varies smoothly with mass.

Analysis of the escape in systems with four exit channels
Mathematical Methods in the Applied Sciences, Volume 46, Issue 1, Page 1032-1044, 15 January 2023., 2023 In this paper, we have performed a numerical investigation of the escape of a particle from two different dynamical systems with the same number of exit channels. We have chosen specific values of the parameters of the systems so that the openings of the potential well in both systems are approximately of the same size.

The Impact of GRBs on Exoplanetary Habitability
Universe, 2023 Can high-energy transient events affect life on a planet? We provide a review of the works that have tried to answer this question. It is argued that that gamma ray bursts, specifically those of the long class, are among the most dangerous astrophysical ...

Quenched Galaxies in Clusters of Galaxies and Their Outskirts [PDF]
Astrophysical Bulletin, 2020 Based on the SDSS data, the properties of galaxies with quenched star formation (QGs) within the "splashback"-radius of galaxy clusters $R_{\rm sp}$ and beyond it have been studied.

The Host Galaxy and Redshift of the Repeating Fast Radio Burst FRB 121102 [PDF]
, 2017 The precise localization of the repeating fast radio burst (FRB 121102) has provided the first unambiguous association (chance coincidence probability p ≲ 3 × 10−4) of an FRB with an optical and persistent radio counterpart.

Galaxy And Mass Assembly (GAMA) blended spectra catalogue: strong galaxy-galaxy lens and occulting galaxy pair candidates [PDF]
, 2015 We present the catalogue of blended galaxy spectra from the Galaxy And Mass Assembly (GAMA) survey. These are cases where light from two galaxies are significantly detected in a single GAMA fibre.

Galaxy: a platform for interactive large-scale genome analysis.
Genome Research, 2005 Accessing and analyzing the exponentially expanding genomic sequence and functional data pose a challenge for biomedical researchers. Here we describe an interactive system, Galaxy, that combines the power of existing genome annotation databases with a ...
