HI Gas in Disk and Dwarf Galaxies in the Semi-analytic Models of Galaxy Formation†

Proceedings of the International Astronomical Union, 2015
We construct the radially-resolved semi-analytic models of galaxy formation based on the L-Galaxies model framework, which include both atomic and molecular gas phase in ISM. The models run on the halo outputs of ΛCDM cosmology N-body simulation.

Forged in FIRE: cusps, cores and baryons in low-mass dwarf galaxies [PDF]

, 2015
We present multiple ultrahigh resolution cosmological hydrodynamic simulations of M_★ ≃ 10^(4–6.3) M_⊙ dwarf galaxies that form within two M_(vir) = 10^(9.5–10) M_⊙ dark matter halo initial conditions.

A Brief, Biased View of Neutron Star Cooling

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT This is a concise and non‐technical review of topics related to neutron star (NS) cooling, for both young NSs and NSs in low‐mass x‐ray binaries. Neutrino emission from the NS core drives cooling rates, via different processes including Urca processes and pair breaking and formation at the neutron superfluid critical temperature.

Modeling the Emission and Polarization Properties of Pulsating Ultraluminous X‐Ray Sources

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT Pulsating Ultraluminous X‐ray Sources (PULXs) are a class of extragalactic sources with high X‐ray luminosity, in excess of 1039$$ {10}^{39} $$ erg s−1$$ {\mathrm{s}}^{-1} $$, and showing pulsations that associate them with neutron stars accreting at a super‐Eddington rate.

Lionel Munby, Marxism, and Local History

History, Volume 110, Issue 389, Page 88-111, January 2025.
Abstract A member of the Communist Party for thirty‐four years, and a key participant in the post‐War Communist Party Historians’ Group, Lionel Munby (1918–2009) is not among that Group's best‐known historians. Yet arguably he was more typical of its membership and outlook.

A search for LSB dwarf galaxies in various environments [PDF]

arXiv, 2003
The varying dwarf galaxy populations in different environments poses a problem for Cold Dark Matter (CDM) hierarchical clustering models. In this paper we present results from a survey conducted in different environments to search for low surface brightness (LSB) dwarf galaxies.

Commodity risk assessment of Betula pendula and Betula pubescens plants from the UK

EFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Betula pendula and B.

JWST imaging of the closest globular clusters—I. Possible infrared excess among white dwarfs in NGC 6397

Astronomische Nachrichten, Volume 345, Issue 6-7, July-August 2024.
Abstract We present James Webb Space Telescope observations of the globular cluster NGC 6397 and use them to extend to infrared wavelengths the characterization of the cluster's entire white dwarf (WD) cooling sequence (CS). The data allows us to probe fundamental astrophysical WD properties and to search for evidence in their colors for (or against ...

Constraining stellar tidal quality factors from planet‐induced stellar spin‐up

Astronomische Nachrichten, Volume 345, Issue 5, June 2024.
Abstract The dynamical evolution of tight star‐planet systems is influenced by tidal interactions between the star and the planet, as was shown recently. The rate at which spins and orbits in such a system evolve depends on the stellar and planetary tidal dissipation efficiency. Here, we present a method to constrain the modified tidal quality factor Q*

Advancing rare cancer research by MALDI mass spectrometry imaging: Applications, challenges, and future perspectives in sarcoma

PROTEOMICS, Volume 24, Issue 12-13, June 2024.
Abstract MALDI mass spectrometry imaging (MALDI imaging) uniquely advances cancer research, by measuring spatial distribution of endogenous and exogenous molecules directly from tissue sections. These molecular maps provide valuable insights into basic and translational cancer research, including tumor biology, tumor microenvironment, biomarker ...
