Asymmetries in stellar streams induced by a galactic merger

open access: yesAstronomy & Astrophysics
Stellar streams are sensitive to perturbations from, for example, giant molecular clouds, bars and spiral arms, infalling dwarf galaxies, or globular clusters which can imprint gaps, clumps, spurs, and asymmetries in tails.

Galaxy interactions and the stimulation of nuclear activity

open access: yes, 1990
The author discusses the idea that interactions between galaxies can lead to enhanced galactic activity. He discusses whether, apart from the observational evidence, there is a strong theoretical or heuristic motivation for investigating galaxy ...

How Many Worlds Could There Be? David Lewis and Advanced Modalizing

open access: yesAnalytic Philosophy, EarlyView.
ABSTRACT Advanced modalizing, namely, possibilities and necessities concerning modal space itself, is problematic for a Lewis‐style analysis of modality. A popular solution, proposed by Divers, postulates explicit semantic clauses for a collapse of advanced modalizing, to the conclusion that all such matters are, if true in the first place, both ...

Low-mass Galaxy Interactions Trigger Black Hole Activity

open access: yesThe Astrophysical Journal Letters
The existence of high- z overmassive supermassive black holes represents a major conundrum in our understanding of black hole evolution. In this Letter, we probe from the observational point of view how early Universe environmental conditions could have ...

Is Less More? Field Evidence on the Impact of Anti‐Bribery Policies on Employee Knowledge and Corrupt Behavior

open access: yesRegulation &Governance, EarlyView.
ABSTRACT Companies increasingly adopt internal norms to enhance compliance with legal rules. However, the rapid growth in volume and complexity of such internal rules may obstruct employee knowledge and understanding of such internal rules, and therefore also their compliance.

Living with Neighbors. VI. Unraveling the Dual Impact of Bars on Star Formation in Paired Galaxies Using DESI

open access: yesThe Astrophysical Journal
We present a comprehensive investigation into the influence of stellar bars on star formation (SF) in galaxy pairs, using a large sample of low-redshift galaxies (0.02 < z < 0.08) from the DESI Legacy Imaging Surveys Data Release 8. Our analysis examines

Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

open access: yesExperimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Interaction of Galaxies with the ICM

open access: yes, 2003
In recent years a wealth of data and detailed hydrodynamical simulations have appeared that show the effects of interactions between the ICM and galaxies. Single dish observations show that cluster galaxies are deficient in their HI content out to 2 Abell radii. The deficient galaxies tend to be on radial orbits.
