Galaxies and dark matter

open access: yes, 2021
What’s the interplay between dark matter and baryons? Luminous and dark matter in massive galaxies. Implications for massive galaxy formation. Implications for the stellar IMF. Implications for Ho. Strong gravitational lenses provide unique insights into the structure of galaxies (and cosmology).

Harnessing Bulk‐Segregant Mapping to Identify Trait‐Associated Genes in the Allopolyploid Model Plant Nicotiana benthamiana

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Forward genetics has been instrumental in identifying genes underlying desirable traits, yet its application to polyploid plants, many of which are key agricultural crops, remains challenging due to their genomic complexity. Therefore, we developed BenthMap, a bulk segregant analysis platform for high‐throughput trait mapping and gene ...

Discovery of a galaxy associated with the HI cloud FAST J0139+4328

open access: yesAstronomy & Astrophysics
The search for “dark galaxies”, a key prediction of the lambda cold dark matter, has yielded few viable candidates. Recently, FAST J0139+4328 was reported as the first isolated dark galaxy in the nearby universe, based on a neutral hydrogen (HI ...

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

open access: yesExperimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.

Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental 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 ...

Dark Matter Distribution in Milky Way analog Galaxies

open access: yesThe Astrophysical Journal
Our current understanding of how dark matter (DM) is distributed within the Milky Way (MW) halo, particularly in the solar neighborhood, is based on either careful studies of the local stellar orbits, model assumptions on the global shape of the MW halo,

Coma Galaxy Cluster Determination of the Neutrino Mass Scale and the KATRIN Wrong Calculations

open access: yesReports in Advances of Physical Sciences
A second estimate of the neutrino mass scale, using the Coma Galaxy Cluster, is made. The first estimate used an approximate value of its Dark Matter mass, from weak gravitational lensing [Peter D. Morley, Prediction of the neutrino mass scale using Coma
