Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.Abstract The geology of a potential Artemis landing site on Mons Malapert is examined using remote sensing techniques and lessons learned from Apollo missions to the lunar surface. Orthomosaics, digital terrain models, illumination models, thermal conditions, crater size‐frequency distribution analyses, geomorphological mapping, spectral and ...

Antinuclei from primordial black holes
Physical Review DLight primordial black holes (PBHs) may have originated in the early Universe, and could contribute to the dark matter in the Universe. Their Hawking evaporation into particles could eventually lead to the production of antinuclei, which propagate and arrive at Earth as cosmic rays with a flux peaked at GeV energies.

Schwarzschild black holes can wear scalar wigs
, 2012 We study the evolution of a massive scalar field surrounding a Schwarzschild black hole and find configurations that can survive for arbitrarily long times, provided the black hole or the scalar field mass is small enough. In particular, both ultra-light

Seguir adelante: A qualitative exploration of Latino farmworkers' work and nonwork resources
American Journal of Community Psychology, Volume 75, Issue 3-4, Page 475-488, June 2025.Abstract Latino immigrant workers have been an exploited community within many dangerous workforces, but especially within the agricultural industry. They are a crucial population for the labor and economy of the U.S., yet Latino farmworkers report feeling expendable, discriminated against, and exposed to hazardous working conditions.

Primordial black hole minimum mass
Physical Review D, 2006 In this paper we revisit thermodynamic constraints on primordial black hole (PBH) formation in the early universe. Under the assumption that PBH mass is equal to the cosmological horizon mass, one can use the 2nd Law of Thermodynamics to put a lower limit on the PBH mass.

Primordial black holes from first-order cosmological phase transitions
Physics Letters BWe discuss the possibility of forming primordial black holes during a first-order phase transition in the early Universe. As is well known, such a phase transition proceeds through the formation of true-vacuum bubbles in a Universe that is still in a ...

René Girard's Revision and Misapprehension of Psychoanalysis
International Journal of Applied Psychoanalytic Studies, Volume 22, Issue 2, June 2025.ABSTRACT René Girard's theories of mimetic desire, religious sacrifice, and violence have been immensely provocative and influential. His ways of framing literary desire and conflict are fascinating, as they illustrate how desire and rivalry unleashed lead to violence and derangement.

Primordial black hole formation [PDF]
Proceedings of Black Holes in General Relativity and String Theory — PoS(BHs, GR and Strings), 2009 This work is a review of our main results obtained from general relativistic numerical computations of primordial black-hole formation during the radiation-dominated era of the universe. As initial conditions we consider supra-horizon-scale perturbations of a type which could have come from inflation, with only a growing component and no decaying ...
