Constraints on Cosmic Strings Using Data from the Third Advanced LIGO-Virgo Observing Run. [PDF]

open access: yesPhysical Review Letters, 2021
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time,

Cosmic protons [PDF]

open access: yesPhysics Letters B, 2000
The primary proton spectrum in the kinetic energy range 0.2 to 200 GeV was measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS–91 at an altitude of 380 km. The complete data set combining three shuttle attitudes and including all known systematic effects is ...

A review on natural background radiation

open access: yesAdvanced Biomedical Research, 2013
The world is naturally radioactive and approximately 82% of human-absorbed radiation doses, which are out of control, arise from natural sources such as cosmic, terrestrial, and exposure from inhalation or intake radiation sources.

Ionospheric correction of GPS radio occultation data in the troposphere [PDF]

open access: yesAtmospheric Measurement Techniques, 2016
For inversions of the GPS radio occultation (RO) data in the neutral atmosphere, this study investigates an optimal transition height for replacing the standard ionospheric correction using the linear combination of the L1 and L2 bending angles with the ...

First results from the TNG50 simulation: the evolution of stellar and gaseous discs across cosmic time [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We present a new cosmological, magnetohydrodynamical simulation for galaxy formation: TNG50, the third and final instalment of the IllustrisTNG project. TNG50 evolves 2 × 21603 dark matter particles and gas cells in a volume 50 comoving Mpc across.

Cosmic hysteresis [PDF]

open access: yesThe Fourteenth Marcel Grossmann Meeting, 2017
Cosmological hysteresis, has interesting and vivid implications in the scenario of a cyclic bouncy universe. This, purely thermodynamical in nature, is caused by the asymmetry in the equation of state parameter during expansion and contraction phase of the universe, due to the presence of a single scalar field.

Cosmic Influence on the Sun-Earth Environment

open access: yesSensors, 2008
SOHO satellite data reveals geophysical changes before sudden changes in the Earth's Sun-Earth environment. The influence of extragalactic changes on the Sun as well as the Sun-Earth environment seems to be both periodic and episodic.
