Orbital Modulation of Gamma Rays up to 100 TeV from LS 5039
The Astrophysical Journal LettersGamma-ray binaries are luminous in gamma rays, composed of a compact object orbiting a massive companion star. The interaction between these two objects can drive relativistic outflows, either jets or winds, in which particles can be accelerated to ...

Anisotropic Solutions For Orbifold Moduli From Duality Invariant Gaugino Condensates
, 1994 The values of the $T$ and $U$ moduli are studied for those ${\bf Z}_N $ Coxeter orbifolds with the property that some of the twisted sectors have fixed planes for which the six-torus ${\bf T}^6 $ can not be decomposed into a direct sum ${\bf T}^2 ...

The Astrophysical Journal LettersWe present a pattern emerging from stellar obliquity measurements in single-star systems: planets with high planet-to-star mass ratios ( M _P / M _* ≥ 2 × 10 ^−3 )—such as super-Jupiters, brown dwarf companions, and M dwarfs hosting Jupiter-like planets ...

Slotting Allowances and Retail Product Variety under Oligopoly [PDF]
Slotting fees are fixed charges paid by food manufacturers to retailers for access to the retail market. The role of the practice and its effects on market efficiency are highly controversial.

New realizations of modular forms in Calabi-Yau threefolds arising from $\phi^4$ theory
, 2018 It has been found experimentally by Brown and Schnetz that the number of points over ${\mathbb F}_p$ of a graph hypersurface is often related to the coefficients of a modular form.

Towards Field Theory Amplitudes From the Cohomology of Pure Spinor Superspace
, 2010 A simple BRST-closed expression for the color-ordered super-Yang-Mills 5-point amplitude at tree-level is proposed in pure spinor superspace and shown to be BRST-equivalent to the field theory limit of the open superstring 5-pt amplitude.

High-z Stellar Masses Can Be Recovered Robustly with JWST Photometry
The Astrophysical Journal LettersRobust inference of galaxy stellar masses from photometry is crucial for constraints on galaxy assembly across cosmic time. Here, we test a commonly used spectral energy distribution (SED) fitting code using simulated galaxies from the S phinx ^20 ...

Synergistic degradation of lignocellulose by fungi and bacteria in boreal forest soil [PDF]
, 2015 Thesis (M.S.) University of Alaska Fairbanks, 2015Boreal forests contain an estimated 28% of the world's soil carbon, and currently act as a significant global carbon sink.

The Astrophysical Journal LettersGRB 221009A is the brightest gamma-ray burst (GRB) observed to date. Extensive observations of its afterglow emission across the electromagnetic spectrum were performed, providing the first strong evidence of a jet with a nontrivial angular structure in ...

A New Subclass of Carbon-enhanced Metal-poor Stars at Extremely Low Metallicity
The Astrophysical Journal LettersWe report the discovery of a new subclass of carbon-enhanced metal-poor (CEMP) stars, characterized by high absolute carbon abundances ( A (C) > 7.39) and extremely low metallicity ([Fe/H] ≤ –3.1) but notably lacking enhancements in neutron-capture ...
