SDSS-III Baryon Oscillation Spectroscopic Survey data release 12 : galaxy target selection and large-scale structure catalogues [PDF]

open access: yes, 2016
The Baryon Oscillation Spectroscopic Survey (BOSS), part of the Sloan Digital Sky Survey (SDSS) III project, has provided the largest survey of galaxy redshifts available to date, in terms of both the number of galaxy redshifts measured by a single ...

Gravitational Waves from Nnaturalness

open access: yesJournal of High Energy Physics
We study the prospects for probing the Nnaturalness solution to the electroweak hierarchy problem with future gravitational wave observatories. Nnaturalness, in its simplest incarnation, predicts N copies of the Standard Model with varying Higgs mass ...

Signal identification with Kalman Filter towards background-free neutrinoless double beta decay searches in gaseous detectors

open access: yesJournal of High Energy Physics, 2021
Particle tracks and differential energy loss measured in high pressure gaseous detectors can be exploited for event identification in neutrinoless double beta decay (0νββ) searches.

Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Sociology of Modern Cosmology [PDF]

open access: yes, 2008
Certain results of observational cosmology cast critical doubt on the foundations of standard cosmology but leave most cosmologists untroubled. Alternative cosmological models that differ from the Big Bang have been published and defended by heterodox ...

Colorful particle production at high-energy muon colliders

open access: yesJournal of High Energy Physics
A high-energy μ + μ − collider provides a wide variety of mechanisms for the production of new heavy particles. While the reach for such particles via the direct annihilation of μ + μ − will approach the center-of-mass energy of the collider, the ...

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

Non-standard Models and the Sociology of Cosmology [PDF]

open access: yes, 2013
I review some theoretical ideas in cosmology different from the standard "Big Bang": the quasi-steady state model, the plasma cosmology model, non-cosmological redshifts, alternatives to non-baryonic dark matter and/or dark energy, and others ...
