Shaping the Milky Way: The Interplay of Mergers and Cosmic Filaments
The Astrophysical JournalThe large-scale morphology of Milky Way (MW)–mass dark matter halos is shaped by two key processes: filamentary accretion from the cosmic web and interactions with massive satellites.

The Astrophysical Journal, 2023 The radial acceleration relation (RAR) represents a tight empirical relation between the inferred total and baryonic centripetal accelerations, g _tot = GM _tot (< r )/ r ^2 and g _bar = GM _bar (< r )/ r ^2 , observed in galaxies and galaxy clusters ...

Gravitational Potential Environment of Galaxies: I. Simulation
, 2010 We extend the concept of galaxy environment from the local galaxy number density to the gravitational potential and its functions like the shear tensor.

The Cherenkov Radiation in the Galaxy’s Halo of Dark Matter
International Journal of Astronomy and Astrophysics, 2013 The effect of light refraction in a galaxy halo of dark matter, described by profiles of Navarro-Frenk-White and Burkett, was considered. Powers of the Cherenkov radiation for the refractive indexes of gravitational fields with these profiles were calculated.

ELUCID. V. Lighting Dark Matter Halos with Galaxies [PDF]
The Astrophysical Journal, 2018 Abstract In a recent study, using the distribution of galaxies in the north galactic pole of the SDSS DR7 region enclosed in a 500 box, we carried out our ELUCID simulation (ELUCID III). Here, we light the dark matter halos and subhalos in the reconstructed region in the simulation with ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The origin of galaxy scaling laws in LCDM
, 2018 It has long been recognized that tight relations link the mass, size, and characteristic velocity of galaxies. These scaling laws reflect the way in which baryons populate, cool, and settle at the center of their host dark matter halos; the angular ...

On the clustering of compact galaxy pairs in dark matter haloes [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We analyse the clustering of photometrically selected galaxy pairs by using the halo-occupation distribution (HOD) model. We measure the angular two-point auto-correlation function, ω(θ), for galaxies and galaxy pairs in three volume-limited samples and develop an HOD to model their clustering.

Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.
