The unusual distribution of molecular gas and star formation in Arp 140 [PDF]
, 2006 We investigate the atomic and molecular interstellar medium and star formation of NGC 275, the late-type spiral galaxy in Arp 140, which is interacting with NGC 274, an early-type system.

The evolution of superluminous supernova LSQ14mo and its interacting host galaxy system [PDF]
, 2016 We present and analyse an extensive dataset of the superluminous supernova (SLSN) LSQ14mo (z = 0.256), consisting of a multi-colour light curve from −30 d to +70 d in the rest-frame (relative to maximum light) and a series of six spectra from PESSTO ...

Pre-existing dwarfs, tidal knots and a tidal dwarf galaxy: an unbiased H i study of the gas-rich interacting galaxy group NGC 3166/9 [PDF]
, 2012 We present Arecibo Legacy Fast ALFA (ALFALFA) and follow-up Giant Metrewave Radio Telescope (GMRT) H _I observations of the gas-rich interacting group NGC 3166/9.

TeV Diffuse Emission From the Inner Galaxy
Frontiers in Astronomy and Space Sciences, 2018 The TeV diffuse emission from the Galactic plane is produced by multi TeV electrons and nuclei interacting with radiation fields and ambient gas, respectively. Measurements of the TeV diffuse emission help constrain CR origin and transport properties. We

S8 Tension in the Context of Dark Matter–Baryon Scattering
The Astrophysical Journal Letters, 2023 We explore an interacting dark matter (IDM) model that allows for a fraction of dark matter (DM) to undergo velocity-independent scattering with baryons. In this scenario, structure on small scales is suppressed relative to the cold DM scenario.

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.

LONG-TERM SPECTRAL VARIATIONS OF ULTRALUMINOUS X-RAY SOURCES IN THE INTERACTING GALAXY SYSTEMS M 51 AND NGC 4490/85 [PDF]
, 2010 Variable ultraluminous X-ray sources (ULXs), which are considered to be black hole binaries (BHBs), are known to show state transitions similar to Galactic BHBs.

The Larson-Tinsley Effect in the UV: Interacting vs. `Normal' Spiral Galaxies
, 2010 We compare the UV-optical colors of a well-defined set of optically-selected pre-merger interacting galaxy pairs with those of normal spirals. The shorter wavelength colors show a larger dispersion for the interacting galaxies than for the spirals.
