The Astrophysical Journal, 2023 The host galaxies of tidal disruption events (TDEs) have been shown to possess peculiar properties, including high central light concentrations, unusual star formation histories, and “green” colors.

Halo Spin from Primordial Inner Motions
The Open Journal of Astrophysics, 2020 The standard explanation for galaxy spin starts with the tidal-torque theory (TTT), in which an ellipsoidal dark-matter protohalo, which comes to host the galaxy, is torqued up by the tidal gravitational field around it.

ALMA Resolves the First Strongly Lensed Optical/Near-IR-dark Galaxy
The Astrophysical Journal, 2023 We present high-resolution (≲0.″1) Atacama Large Millimeter/submillimeter Array observations of the strongly lensed galaxy HATLASJ113526.2-01460 at redshift z ∼ 3.1, discovered in the GAMA 12th field of the Herschel-ATLAS survey.

Peculiar Galaxies and Radio Sources
Science, 1966 Pairs of radio sources which are separated by from 2° to 6° on the sky have been investigated. In a number of cases peculiar galaxies have been found approximately midway along a line joining the two radio sources. The central peculiar galaxies belong mainly to a certain class in the recently compiled Atlas of Peculiar Galaxies

Phase-Space Correlations among Systems of Satellite Galaxies
Galaxies, 2021 Driven by the increasingly complete observational knowledge of systems of satellite galaxies, mutual spatial alignments and relations in velocities among satellites belonging to a common host have become a productive field of research.

Peculiar Velocities of Nearby Galaxies [PDF]
Proceedings of the International Astronomical Union, 2006 Over the last five years, enormous progress in accurate distance measurements for nearby galaxies has been attained. The Hubble Space Telescope allows us to estimate distances of about 7–10% accuracy using red giant branch (RGB) up to 8 Mpc. Now we have very accurate distances for more than 200 galaxies within ~6 Mpc.

Revealing Hidden Cosmic Flows through the Zone of Avoidance with Deep Learning
The Astrophysical JournalWe present a refined deep-learning-based method to reconstruct the 3D dark matter density, gravitational potential, and peculiar velocity fields in the Zone of Avoidance (ZOA), a region near the Galactic plane with limited observational data.

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.
