Humanized immune system animal models and their recent applications

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In this review, we provide an updated and comprehensive overview of the current state of humanized immune system animal model research. We discuss the variety of techniques used to produce humanized mice with their respective strengths and weaknesses, and evaluate the advantages and limitations of these models, including issues with incomplete immune ...

N-body simulations of gravitational redshifts and other relativistic distortions of galaxy clustering

open access: yes, 2017
Large redshift surveys of galaxies and clusters are providing the first opportunities to search for distortions in the observed pattern of large-scale structure due to such effects as gravitational redshift.

VMC galaxy structures

open access: yes, 2019
Formation and evolution of galaxies are mainly driven by mergers/interactions. In low red shift, minor mergers play a significant role. It is believed that they are the fundamental components in the formation of the halo of galaxies like Milky Way and in building the outskirts of massive elliptical galaxies. The signatures of these mergers/interactions

The THESEUS Space Mission and the Infrared Telescope Calibration Unit

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Velocity Structure Diagnostics of Simulated Galaxy Clusters

open access: yes, 2010
Gas motions in the hot intracluster medium of galaxy clusters have an important effect on the mass determination of the clusters through X-ray observations.

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

The edge of the Milky Way’s star-forming disc: Evidence from a ’U-shaped’ stellar age profile

open access: yesAstronomy & Astrophysics
We leveraged reliable age and distance estimates from LAMOST-DR3 and APOGEE-DR17+AstroNN combined with Gaia data to perform a detailed analysis of the stellar age distribution in the Milky Way’s (MW) outer disc using giant stars. Selecting stars near the

THE ROLE OF POOR GALAXY CLUSTERS FOR STUDYING SUPERCLUSTER STRUCTURE

open access: yesOdessa Astronomical Publications, 2008
The distribution of galaxy clusters is analyzed in regions of 6 galaxy superclusters with both measured and estimated redshifts. The positions of ACO and APM galaxy clusters in the regions are compared with the positions of galaxy clusters and groups ...

Chandra Observations of A2670 and A2107: A Comet Galaxy and cDs with Large Peculiar Velocities

open access: yes, 2005
We present an analysis of Chandra observations of the galaxy clusters A2670 and A2107. Their cD galaxies have large peculiar velocities (>200km/s) and thus the clusters appear to be undergoing mergers.

Structure and Evolution of Regular Galaxies

open access: yes, 2021
This is English translation of the Thesis, originally written in Russian and remained unpublished. The Thesis was an attempt to combine data from three previously independent areas: the structure and kinematics of stellar populations of the Galaxy, photometric and dynamical models of galaxies, and models of the dynamical and physical evolution of ...
