Unprecedented Multipoint Observation of Spatially Varying ICME Turbulence of Different Ages during October 2024 Extreme Solar Storm at 1 AU
Shibotosh Biswas, Ankush Bhaskar, SG Abitha +4
Understanding turbulence in interplanetary coronal mass ejections (ICMEs) is fundamental to space plasma research and critical for assessing the impact of space weather on geospace…
Evidence of energy conversion in weakly collisional plasma during an interplanetary coronal mass ejection
Omkar Dhamane, Anil Raghav, Simone Benella +14
Intervals of enhanced turbulent fluctuations are typically less frequent within the magnetic cloud region of an interplanetary coronal mass ejection (ICME). We investigate two such…
Magnetic Moment-Field Interactions, A Universal Mechanism for Particle Energization
Anil Raghav, Ajay Kumar, Mariyam Karari +4
Magnetic reconnection is a pivotal mechanisms in the energization and heating of cosmic plasmas, yet the exact process of energy transfer during these events remain elusive. Tradit…
Humanity's Last Exam
Long Phan, Alice Gatti, Ziwen Han +1168
Benchmarks are important tools for tracking the rapid advancements in large language model (LLM) capabilities. However, benchmarks are not keeping pace in difficulty: LLMs now achi…
Quasi-planar ICME sheath: a cause of first two-step extreme geomagnetic storm of 25th solar cycle observed on 23 April 2023
Kalpesh Ghag, Anil Raghav, Ankush Bhaskar +5
Interplanetary Coronal Mass Ejections (ICMEs) are prominent drivers of space weather disturbances and mainly lead to intense or extreme geomagnetic storms. The reported studies sug…
Observational Validation of Cosmic Ray Acceleration Hypothesis
Anil Raghav, Kalpesh Ghag, Omkar Dhamane +3
Despite centuries of rigorous theoretical and observational research, the origin and acceleration mechanism of Galactic Cosmic Rays (GCRs) remain a mystery. In 1949, Fermi proposed…
First analysis of in-situ observation of surface Alfvén waves in ICME flux rope
Anil Raghav, Omkar Dhamane, Zubair Shaikh +8
Alfvén waves (AWs) are inevitable in space and astrophysical plasma. Their crucial role in various physical processes, occurring in plasma, has triggered intense research in solar-…
Distinct polytropic behavior of plasma during ICME-HSS Interaction
Kalpesh Ghag, Anil Raghav, Zubair Shaikh +3
Interplanetary Coronal Mass Ejections (ICMEs) and High Speed Streams (HSSs) are noteworthy drivers of disturbance of interplanetary space. Interaction between them can cause severa…
In-situ Observation Of Alfv'en Waves In Icme Shock-Sheath Indicates Existence Of Alfv'enic Turbulence
Anil Raghav, Zubair Shaikh, Omkar Dhamane +3
The dynamic evolution of coronal mass ejection (CME) in interplanetary space generates highly turbulent, compressed, and heated shock-sheath. This region furnishes a unique environ…
Observation of Alfven wave in ICME-HSS interaction region
Omkar Dhamane, Anil Raghav, Zubair Shaikh +7
The Alfvén wave (AW) is the most common fluctuation present within the emitted solar wind from the Sun. Moreover, the interaction between interplanetary coronal mass ejection (ICME…
The role of extreme geomagnetic storms in the Forbush decrease profile
Anil Raghav, Prathmesh Tari, Kalpesh Ghag +7
The Forbush decrease (FD) and Geomagnetic storm (GS) are the two distinct space weather events having common causing agents like interplanetary coronal mass ejection (ICME) or coro…
