We report the observation of a compact binary coalescence involving a 22.2�24.3 M ? black hole and a compact object with a mass of 2.50�2.67 M ? (all measurements quoted at the 90% credible level). The gravitational-wave ...
A thermal gradient and/or a chemical potential gradient in a conducting medium can lead to an electric field, an effect known as thermoelectric effect or Seebeck effect. In the context of heavy-ion collisions, we estimate ...
The cross-section for the lowest order 2\rightarrow 2 elastic scattering between two charged scalars under external magnetic field mediated via a neutral scalar, has been computed in strong as well as weak magnetic field ...
Observations of the temperature anisotropies in the Cosmic Microwave Back-ground (CMB) radiation show that the models of inflation with the monomial potentials areinconsistent with the allowedns?rbounds. However ...

Studies of bibliographic data suggest a strong correlation between the growth of citation networks and their corresponding co-authorship networks. We explore the interdependence between evolving citation and co-authorship ...

Martian gullies are landforms comprising an alcove, channel and debris apron. In some gullies lobate deposits have been observed, implying a debris-flow-like process, but uncertainty remains as to the importance of this ...
The drag and diffusion coefficients are studied within the framework of Fokker-Planck dynamics for the case of a charm quark propagating in an expanding quark-gluon plasma. The space-time evolution of the nuclear matter ...

We study the constraints on primordial magnetic fields (PMFs) in the light of Experiment to Detect the Global Epoch of Reionization Signature (EDGES) low-band observation and Absolute Radiometer for Cosmology, Astrophysics ...

Solar flares are known to generate seismic waves in the Sun. We present a detailed analysis of seismic emission in sunspots accompanying M- and X-class solar flares. For this purpose, we have used high-resolution Dopplergrams ...

In this paper, we present a comprehensive study of the evolutionary phases of a major M6.6 long duration event with special emphasize on its pre-flare phase. The event occurred in NOAA 12371 on 2015 June 22. A remarkable ...

We study the 21-cm differential brightness temperature in the presence of primordial helical magnetic fields for redshift z = 10�30. We argue that the ?-effect that sets in at earlier time can be helpful in lowering the ...
We report new exposures of water?ice along the scarps wall located within craters in the northern mid?latitude region of Mars using high?resolution imagery and spectral data of Mars Reconnaissance Orbiter. The exposed ...

Ambient concentrations of benzene, toluene, and carbon-monoxide (CO) were measured at a semi-urban site in western India during the year 2015. Monthly mixing ratios of benzene, toluene, and CO were in the ranges of 0.58�1.18, ...

Herein, we report the use of a dual emitting quantum dot complex (QDC; composed of a blue emitting metal-methylsalicylaldimine complex on the surface of an orange emitting Mn2+-doped ZnS quantum dot) for ratiometric and ...
In this work, we study the visible photon production from the viscous dissipation of the dark matter (DM) fluid. The generation of visible photons depends on the magnitude of the dark matter viscosity and becomes important ...
