Mapping Extragalactic Dark Matter Annihilation with Galaxy Surveys: A Systematic Study of Stacked Group Searches [PDF]
, 2018 Dark matter in the halos surrounding galaxy groups and clusters can annihilate to high-energy photons. Recent advancements in the construction of galaxy group catalogs provide many thousands of potential extragalactic targets for dark matter.

The Orientation of Galaxies in Nearby Galaxy Groups [PDF]
Symposium - International Astronomical Union, 2004 The statistical analysis of six nearby groups of galaxies, connected with the Milky Way, M31, M81, M101, NGC5128 and NGC5236 shows an isotropic distribution of galaxy planes, similarly to galaxies within the Local Group. Also planes of galaxies in the nearby (Vr < 500 km s−1) region of the Local Supercluster exhibit random distribution, disregarding

ChemCatChem, Accepted Article.Publishing supporting data significantly impacts researchers' productivity, especially in experiments requiring extensive tracking of data, processing steps, parameters, and outputs. A managed workflow environment, combined with RO‐Crates, addresses these data management challenges. Workflows provide an alternative for handling complex data analyses by

Pavo: Discovery of a Star-forming Dwarf Galaxy Just Outside the Local Group
The Astrophysical Journal Letters, 2023 We report the discovery of Pavo, a faint ( M _V = −10.0), star-forming, irregular, and extremely isolated dwarf galaxy at D ≈ 2 Mpc. Pavo was identified in Dark Energy Camera Legacy Survey imaging via a novel approach that combines low surface brightness

Multiwavelength Observations of the Second Largest Known FR II Radio Galaxy, NVSS 2146+82 [PDF]
, 2000 We present multi-frequency VLA, multicolor CCD imaging, optical spectroscopy, and ROSAT HRI observations of the giant FR II radio galaxy NVSS 2146+82. This galaxy, which was discovered by the NRAO VLA Sky Survey (NVSS), has an angular extent of nearly 20'

Supernovae in isolated galaxies, in pairs and in groups of galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 In order to investigate the influence of the environment on the supernova (SN) production we have performed a statistical investigation of the SNe discovered in isolated galaxies, in pairs and in groups of galaxies. 22 SNe in 18 isolated galaxies, 48 SNe in 40 galaxies members of 37 pairs and 211 SNe in 170 galaxies members of 116 groups have been ...

On the Root Cause of the Host “Mass Step” in the Hubble Residuals of Type Ia Supernovae
The Astrophysical Journal, 2023 It is well established that the Hubble residuals of Type Ia supernovae (SNe Ia) show the luminosity step with respect to their host galaxy stellar masses.

A review of multiscale numerical modeling of rock mechanics and rock engineering
Deep Underground Science and Engineering, EarlyView.Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...
