Journal of the Association for Information Science and Technology, EarlyView.Abstract Provenance is the story of how something has come to be. In this paper, we provide a systematic literature review to categorize the various notions of provenance in Information Sciences. The goal of this review is to paint a broader picture of the multiple uses of provenance at play and to enhance our understanding of the importance of ...

The M31–M33 Interaction: Impact on M31’s Center-of-mass Motion and Satellite Orbits
The Astrophysical JournalInspired by recent studies of the interaction between the Milky Way and the Large Magellanic Cloud and its implications for the Milky Way’s global dynamical history, we investigate how the massive satellite galaxy M33 influences the position and velocity

DISCRETE X-RAY SOURCES IN GALAXY CLUSTERS
Odessa Astronomical Publications, 2020 Current studies of extragalactic X-ray sources using data from orbital observatory XMM- Newton are at the front line of X-ray astronomy. Resolution capacity of the observatory instruments enable to detect separate X-ray sources in the close galaxies.

The Orientation of Galaxies in Nearby Galaxy Groups [PDF]
Symposium - International Astronomical Union, 2004 The statistical analysis of six nearby groups of galaxies, connected with the Milky Way, M31, M81, M101, NGC5128 and NGC5236 shows an isotropic distribution of galaxy planes, similarly to galaxies within the Local Group. Also planes of galaxies in the nearby (Vr < 500 km s−1) region of the Local Supercluster exhibit random distribution, disregarding

CG J1720-67.8: A Detailed Analysis of Optical and Infrared Properties of a New Ultracompact Group of Galaxies [PDF]
, 2002 We present here optical spectroscopy and BVRJHK(s) photometry of the recently discovered ultra-compact group of galaxies CG J1720-67.8. This work represents a considerable extension of the preliminary results we presented in a previous paper. Despite the

Astronomische Nachrichten, EarlyView.ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

A Massive Quiescent Galaxy in a Group Environment at z = 4.53
The Astrophysical JournalWe report on the spectroscopic confirmation of a massive quiescent galaxy at z _spec = 4.53 in the COSMOS field. The object was first identified as a galaxy with suppressed star formation at z _phot ∼ 4.65 from the COSMOS2020 catalog.

A statistical study of the luminosity gap in galaxy groups
, 2010 The luminosity gap between the two brightest members of galaxy groups and clusters is thought to offer a strong test for the models of galaxy formation and evolution.
