Quantifying the Toroidal Flux of Pre-existing Flux Ropes of CMEs
C. Xing, X. Cheng, Jiong Qiu +3
In past decades, much progress has been achieved on the origin and evolution of coronal mass ejections (CMEs). In-situ observations of the counterparts of CMEs, especially magnetic…
First passage time in multi-step stochastic processes with applications to dust charging
Babak Shotorban
An approach was developed to describe the first passage time (FPT) in multistep stochastic processes with discrete states governed by a master equation (ME). The approach is an ext…
PIC simulation of a shock tube: Implications for wave transmission in the heliospheric boundary region
S. Matsukiyo, T. Noumi, G. P. Zank +2
A shock tube problem is solved numerically by using one-dimensional full particle-in-cell simulations under the condition that a relatively tenuous and weakly magnetized plasma is…
Hot WHIM counterparts of FUV OVI absorbers: Evidence in the line-of-sight towards quasar 3C 273
Jussi Ahoranta, Jukka Nevalainen, Nastasha Wijers +7
We explore the high spectral resolution X-ray data towards the quasar 3C273 to search for signals of hot ( K) X-ray-absorbing gas co-located with two established inte…
Distribution of the C statistic with applications to the sample mean of Poisson data
M. Bonamente
The C statistics, also known as the Cash statistic, is often used in astronomy for the analysis of low-count Poisson data. One of the challenges of the C statistic is that its prob…
Predicting the Solar Wind at Parker Solar Probe Using an Empirically Driven MHD Model
T. K. Kim, N. V. Pogorelov, C. N. Arge +20
Since the launch on 2018/08/12, Parker Solar Probe (PSP) has completed its first and second orbits around the Sun, having reached down to 35.7 solar radii at each perihelion. In an…
Turbulence Transport Modeling and First Orbit Parker Solar Probe (PSP) Observations
Laxman Adhikari, Gary P. Zank, Lingling Zhao +8
Parker Solar Probe (PSP) achieved its first orbit perihelion on November 6, 2018, reaching a heliocentric distance of about 0.165 au (35.55 R). Here, we study the evolution…
Identification of Magnetic Flux Ropes from Parker Solar Probe Observations during the First Encounter
L. -L. Zhao, G. P. Zank, L. Adhikari +17
The Parker Solar Probe (PSP) observed an interplanetary coronal mass ejection (ICME) event during its first orbit around the sun, among many other events. This event is analyzed by…
Hi-C 2.1 Observations of Small-Scale Miniature-Filament-Eruption-Like Cool Ejections in Active Region Plage
Alphonse C. Sterling, Ronald L. Moore, Navdeep K. Panesar +5
We examine 172 Ang ultra-high-resolution images of a solar plage region from the Hi-C 2.1 ("Hi-C") rocket flight of 2018 May 29. Over its five-minute flight, Hi-C resolves a pletho…
Measuring bulk flows of the intracluster medium in the Perseus and Coma galaxy clusters using XMM-Newton
J. S. Sanders, K. Dennerl, H. R. Russell +7
We demonstrate a novel technique for calibrating the energy scale of the XMM EPIC-pn detector, which allows us to measure bulk flows in the intracluster medium (ICM) of the Perseus…
Heliospheric structure as revealed by the 3 -- 88 keV H ENA spectra
A. Czechowski, M. Bzowski, J. M. Sokół +8
Energetic neutral atoms (ENA) are an important tool for investigating the structure of the heliosphere. Recently, it was observed that fluxes of ENAs (with energy 55 keV) com…
Energy Dissipation and Entropy in Collisionless Plasma
Senbei Du, Gary P. Zank, Fan Guo +1
It is well known that collisionless systems are dissipation free from the perspective of particle collision and thus conserve entropy. On the other hand, processes such as magnetic…
Towards the Avoidance of Counterfeit Memory: Identifying the DRAM Origin
B. M. S. Bahar Talukder, Vineetha Menon, Biswajit Ray +2
Due to the globalization in the semiconductor supply chain, counterfeit dynamic random-access memory (DRAM) chips/modules have been spreading worldwide at an alarming rate. Deployi…
Secure State Estimation and Attack Reconstruction in Cyber-Physical Systems: Sliding Mode Observer Approach
Shamila Nateghi, Yuri Shtessel, Christopher Edwards +1
A cyber-physical system (CPS) is a tight coupling of computational resources, network communication, and physical processes. They are composed of a set of networked components, inc…
Hi-C 2.1 Observations of Jetlet-like Events at Edges of Solar Magnetic Network Lane
