Interacting Dark Energy after DESI Baryon Acoustic Oscillation Measurements. [PDF]
Physical Review LettersWe investigate the implications of the baryon acoustic oscillations measurement released by the Dark Energy Spectroscopic Instrument for interacting dark energy (IDE) models characterized by an energy-momentum flow from dark matter to dark energy.

Hidden interaction in SBO galaxies [PDF]
, 1990 Galaxies, like plants, show a large variety of grafts: an individual of some type connects physically with a neighborhood of same or different type. The effects of these interactions between galaxies have a broad range of morphologies depending, among ...

EXTENDED Lyα EMISSION FROM INTERACTING GALAXIES AT HIGH REDSHIFTS [PDF]
, 2012 Recent observations have discovered a population of extended Lyα sources, dubbed Lyα blobs (LABs), at high redshift z ∼ 2–6.6. These LABs typically have a luminosity of L ∼ 1042–1044 erg s−1, and a size of tens of kiloparsecs, with some giant ones ...

Discovery of a Rare Group of Dwarf Galaxies in the Local Universe
The Astrophysical Journal LettersWe report the discovery of a rare isolated group of five dwarf galaxies located at z = 0.0086 ( D = 36 Mpc). All member galaxies are star forming, blue, and gas rich, with g − r indices ranging from 0.2 to 0.6 mag, and two of them show signs of ongoing ...

Induced star formation in interacting galaxies [PDF]
, 1987 Measurements of H alpha emission line fluxes and FIR fluxes in approx. 100 interacting spirals were used to investigate the effects of close tidal interactions on the disk and nuclear star formation rates in galaxies.

INTERACTING GALAXIES(Proceedings of Japan-France Seminar on Chemical Evolution of Galaxies with Active Star Formation) [PDF]
, 2010 application/pdfThree topics on interacting galaxies are presented. The first is on ring galaxies and bead instability, the second on Seyfert 1 nucelus of a new ring galaxy in Sextans, and the third on dual emission line clouds in the interacting pair Arp

ORDER AND CHAOS IN A THREE-DIMENSIONAL BINARY SYSTEM OF INTERACTING GALAXIES [PDF]
, 2012 We present a galactic gravitational model of three degrees of freedom in order to investigate and reveal the behavior of orbits in a binary quasar system. The two quasars are hosted in a pair of interacting disk galaxies.

Interacting galaxies resolved by IRAS [PDF]
, 1994 We discuss procedures, limitations and results of high resolution processing of interacting galaxies observed by the Infrared Astronomical Satellite (IRAS).

Interacting galaxies in 3D: Three case studies.
, 2015 International audienceWe present 3D observations of three interacting galaxies in order derive their extended kinematics and to trace events such as violent star-formation (SF), mass-transfer, structure perturbation and the presence of energetic sources ...
