Evidence for Ultra-diffuse Galaxy “Formation” through Galaxy Interactions [PDF]
The Astrophysical Journal Letters, 2018 Abstract We report the discovery of two ultra-diffuse galaxies (UDGs) that show clear evidence of an association with tidal material and an interaction with a larger galaxy halo, found during a search of the Wide portion of the Canada–France–Hawaii Telescope Legacy Survey. The two new UDGs, NGC 2708-Dw1 and NGC 5631-Dw1, are faint (M

SIDM on FIRE: hydrodynamical self-interacting dark matter simulations of low-mass dwarf galaxies. [PDF]
Monthly notices of the Royal Astronomical Society, 2017 We compare a suite of four simulated dwarf galaxies formed in 1010 M☉ haloes of collisionless cold dark matter (CDM) with galaxies simulated in the same haloes with an identical galaxy formation model but a non-zero cross-section for DM self-interactions.

PKS2250-41 and the Role of Jet Cloud Interactions in Powerful Radio Galaxies [PDF]
, 1998 We have studied the effects of the interaction between the radio jet and the ambient gas in the powerful radio galaxy PKS2250-41 (z = 0.31). Our results show that the gas has been accelerated, compressed, heated and collisionally ionized by the shock ...

Prevalence of Tidal Interactions among Local Seyfert Galaxies: The Control Experiment [PDF]
, 2008 We test whether there is a relation between the observed tidal interactions and Seyfert activity by imaging in atomic hydrogen (H I 27) inactive galaxies at the same spatial resolution and detection threshold as the Seyfert sample. This control sample of

The evidence for jet-cloud interactions in a sample of high-redshift radio galaxies [PDF]
, 2001 We present detailed long-slit spectroscopic observations of a sample of four powerful radio galaxies, with high redshifts (0 ...

Reignition of star formation in dwarf galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The Local Group hosts a number of star-forming dwarf galaxies that show evidence of periods of little to no star formation. We use a suite of cosmological simulations to study how star formation is reignited in such galaxies.

Scale Interactions and Galaxy Evolution [PDF]
Astrophysics and Space Science, 2003 To understand galaxies and their evolution, it is necessary to describe how the different scales interact: how the microscopic physics, such as star formation, or the large scale physics, such as galaxy interactions may modify the galaxy global shapes.

The large-scale distribution of warm ionized gas around nearby radio galaxies with jet-cloud interactions [PDF]
, 2000 Deep, narrow-band Hα observations taken with the TAURUS Tunable Filter on the 4.2-m William Herschel Telescope are presented for two nearby radio galaxies with strong jet–cloud interactions.

Advanced Healthcare Materials, EarlyView.Novel photo‐clickable triazine‐trione thermosets can be shaped and cured under mild conditions, including room and physiological temperatures. These materials are biocompatible and support osteogenic differentiation of bone marrow–derived mesenchymal stem cells on their surface.

Bar-spheroid interaction in galaxies
The Astrophysical Journal, 1992 The secular evolution of barred galaxies is explored using N-body simulation and linear analysis. In particular, we examine the interaction between bars and spheroidal components of galaxies. According to our calculations, this interaction drives secular transfer of angular momentum from bars to spheroids, primarily through resonant coupling.
