A Timeline of the M81 Group: Properties of the Extended Structures of M82 and NGC 3077

open access: yesThe Astrophysical Journal
Mergers of and interactions between galaxies imprint a wide diversity of morphological, dynamical, and chemical characteristics in stellar halos and tidal streams.

FEASTS: IGM Cooling Triggered by Tidal Interactions through the Diffuse H i Phase around NGC 4631

open access: yesThe Astrophysical Journal, 2023
We use the single-dish radio telescope Five-hundred meter Aperture Spherical Telescope (FAST) to map the H i in the tidally interacting NGC 4631 group with a resolution of 3.′24 (7 kpc), reaching a 5 σ column density limit of 10 ^17.9 cm ^−2 assuming a ...

Study on the Impact of Offshore Wind Farms on Surrounding Water Environment in the Yangtze Estuary Based on Remote Sensing

open access: yesRemote Sensing, 2023
Offshore wind farms (OWFs), built extensively in recent years, induce changes in the surrounding water environment. The changes in the suspended sediment concentration (SSC) and chlorophyll-a concentration (Chl-aC) induced by an OWF in the Yangtze River ...

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

A top-down scenario for the formation of massive Tidal Dwarf Galaxies [PDF]

open access: yes, 2004
Among those objects formed out of collisional debris during galaxy mergers, the prominent gaseous accumulations observed near the tip of some long tidal tails are the most likely to survive long enough to form genuine recycled galaxies.

The Nature of LoBAL QSOs. II. HST/WFC3 Observations Reveal Host Galaxies Dominated by Mergers

open access: yesThe Astrophysical Journal, 2023
Low-ionization broad absorption line QSOs (LoBALs) are suspected to be merging systems in which extreme, active galactic nucleus-driven outflows have been triggered.

Tidal Tail Ejection as a Signature of Type~Ia Supernovae from White Dwarf Mergers

open access: yes, 2013
The merger of two white dwarfs may be preceded by the ejection of some mass in "tidal tails", creating a circumstellar medium around the system. We consider the variety of observational signatures from this material, which depend on the lag time between ...

Microtopography enhances intestinal drug absorption via Piezo1‐mediated tight junction modulation

open access: yesBMEMat, EarlyView.
Microtopography‐driven enhancement of oral peptide drug delivery by activating Piezo1 channels significantly improves paracellular permeability and bioavailability, offering a novel approach for optimizing macromolecule absorption in pharmaceutical formulations.

Globular Cluster Clumpy Tidal Tails

open access: yes, 2012
Tidal tails are interesting structure recently observed around many Globular Clusters. The understanding of the formation of such debris can help to analyse the interplay between internal and external processes in the cluster as well as to probe the potential of the host galaxy where the cluster is orbiting. We report preliminary results of an on-going

Constraining Dark Halo Potentials with Tidal Tails [PDF]

open access: yesThe Astrophysical Journal, 1999
We present an extensive parameter survey to study the influence of halo mass profiles on the development of tidal tails in interacting disk galaxies. We model the galaxies using a fixed exponential disk with a central bulge and vary the halo potential over a range of parameters using both the Hernquist and NFW mass distributions, probing the effect of ...
