Intermittent turbulent fluctuations in solar coronal mass ejections
Apurva Bhagat, Sumit Tambe, Debesh Bhattacharjee +1
Localised regions of high intensity fluctuations are known to be signatures of intermittency in fluid and plasma turbulence. We investigate such turbulent spots using near-Earth {\…
Open Data from LIGO, Virgo, and KAGRA through the Second Part of the Fourth Observing Run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1809
LIGO, Virgo, KAGRA, and GEO 600 form a network of gravitational-wave observatories. Data and analysis results from this network are made publicly available through the Gravitationa…
Energy-Containing Electrons in Solar Flares: Improving Hard X-Ray and EUV Diagnostics
Yingjie Luo, Eduard P. Kontar, Debesh Bhattacharjee
Solar flares effectively accelerate particles to non-thermal energies. These accelerated electrons are responsible for energy transport and subsequent emissions in HXR, radio, and…
Total Power and Low-energy Cut-off Time Evolution of Solar Flare Accelerated Electrons Using X-Ray Observations and Warm-Target Model
Debesh Bhattacharjee, Eduard P. Kontar, Yingjie Luo
A primary characteristic of solar flares is the efficient acceleration of electrons to nonthermal deka-keV energies. While hard X-Ray (HXR) observation of bremsstrahlung emission s…
Proton heating estimates from near-Earth observations of coronal mass ejections in solar cycle 24
Debesh Bhattacharjee, Prasad Subramanian, Saikat majumder +1
As solar coronal mass ejections (CMEs) propagate through the heliosphere, they expend energy in heating protons to compensate for the cooling that occurs due to expansion. CME prop…
Spectroscopy of Supernova Remnants and Candidates in M31
Nelson Caldwell, John C. Raymond, Knox S. Long +1
With a star formation rate of order 0.4 M yr, M31 should have significant population of supernova remnants (SNRs), and, in fact, 156 SNR and SNR candidates have bee…
