Interacting galaxies and mergers

Nature Astronomy, 2019
Two landmark papers in the 1970s contributed strongly to establishing the importance of galaxy interactions and mergers in the formation and evolution of galaxies, using only gravity, and the ensuing dynamical friction.

Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

Environmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

A spectroscopic study of the merging dwarf galaxy PGC 007782

Bibechana
We did a detailed spectroscopic study of PGC 007782, an interacting emission type dwarf galaxy. This study utilized the optical spectrum of emission lines to explore the system of interacting dwarf galaxies.

Saving Bambi from the mower? Using a drone with thermal camera to evaluate a low‐tech scaring technique to reduce roe deer fawn mortality during grass harvest

Wildlife Biology, EarlyView.
Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

Characterizing the Molecular Gas in Infrared Bright Galaxies with CARMA

The Astrophysical Journal
We present the CO(1–0) maps of 28 infrared-bright galaxies from the Great Observatories All-Sky Luminous Infrared Galaxy Survey (GOALS) taken with the Combined Array for Research in Millimeter Astronomy (CARMA).

Preserving evidence integrity in full file system extractions: Assessing hash inconsistencies and potential solutions

Journal of Forensic Sciences, EarlyView.
Abstract Smartphone manufacturers' enhanced privacy and security measures, such as File‐Based Encryption (FBE), have disrupted traditional data extraction techniques, necessitating the adoption of Full File System Extraction (FFS). FFS requires booting a smartphone, decrypting its UserData partition, and accessing files individually, a process that ...

A Compact Protogroup at z ∼ 5: A Massive Galaxy Caught in Formation

The Astrophysical Journal Letters
We report the discovery of SCGG-z5 (nicknamed the Shirui Group), a compact galaxy protogroup at z = 4.97 in the MACS0416 field, identified from the SAPPHIRES Early Data Release. Six members are spectroscopically confirmed via H α emission, spanning 4.96 ≤

Interacting galaxies in the NGC 697 group of galaxies [PDF]

Proceedings of the International Astronomical Union, 2016
AbstractWe studied the morphology of two brightest members of the nearby NGC 697 group of galaxies, and found evidence of satellite accretion onto the primary galaxy NGC 697 of the group as well as outer and inner irregularities of the only early-type galaxy NGC 680 of the group, which are probably shaped by recent dry merging event(s).

Humble beginnings of the Australian giant wood moth (Endoxyla cinereus): A century‐old mystery solved

Insect Science, EarlyView.
The Australian giant wood moth (Endoxyla cinereus) feeds within the galls of scale insects (Apiomorpha) before transitioning into its wood‐boring eucalypt larval phase. This transitionary phase may be key to its multi‐year development, at the end of which it can produce over 100 000 eggs.
