X-ray Emission of the -ray Loud Young Radio Galaxy NGC 3894
K. Balasubramaniam, L . Stawarz, C. C. Cheung +6
The radio source 1146+596 is hosted by an elliptical/S0 galaxy NGC\,3894, with a low-luminosity active nucleus. The radio structure is compact, suggesting a very young age of the j…
Complex Structure of the Eastern Lobe of the Pictor A Radio Galaxy: Spectral Analysis and X-ray/Radio Correlations
R. Thimmappa, Ł. Stawarz, U. Pajdosz-Śmierciak +2
Here we present detailed analysis of the distinct X-ray emission features present within the Eastern radio lobe of the Pictor A galaxy, around the jet termination region, utilising…
Critical Science Plan for the Daniel K. Inouye Solar Telescope (DKIST)
Mark P. Rast, Nazaret Bello González, Luis Bellot Rubio +84
The Daniel K. Inouye Solar Telescope (DKIST) will revolutionize our ability to measure, understand and model the basic physical processes that control the structure and dynamics of…
Chandra View of the LINER-type Nucleus in the Radio-Loud Galaxy CGCG 292-057: Ionized Iron Line and Jet-ISM Interactions
K. Balasubramaniam, L. Stawarz, V. Marchenko +5
We present an analysis of the new, deep (94\,ksec) {\it Chandra} ACIS-S observation of radio-loud active galaxy CGCG\,292057, characterized by a LINER-type nucleus and a complex…
Chandra Imaging of the Western Hotspot in the Radio Galaxy Pictor A: Image Deconvolution and Variability Analysis
R. Thimmappa, Ł. Stawarz, V. Marchenko +3
Here we present an analysis of the X-ray morphology and flux variability of the particularly bright and extended Western hotspot in the nearest powerful (FR II-type) radio galaxy,…
Signatures of the disk-jet coupling in the Broad-line Radio Quasar 4C+74.26
G. Bhatta, L. Stawarz, A. Markowitz +16
Here we explore the disk-jet connection in the broad-line radio quasar 4C+74.26, utilizing the results of the multiwavelength monitoring of the source. The target is unique in that…
The Origin of Sequential Chromospheric Brightenings
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +1
Sequential chromospheric brightenings (SCBs) are often observed in the immediate vicinity of erupting flares and are associated with coronal mass ejections. Since their initial dis…
Comparing SSN Index to X-ray Flare and Coronal Mass Ejection Rates from Solar Cycles 22-24
Lisa M. Winter, Rick Pernak, K. S. Balasubramaniam
The newly revised sunspot number series allows for placing historical geoeffective storms in the context of several hundred years of solar activity. Using statistical analyses of t…
Qualities of Sequential Chromospheric Brightenings Observed in Optical and UV Images
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +1
Chromospheric flare ribbons observed in H-alpha appear well-organized when first examined: ribbons impulsively brighten, morphologically evolve, and exponentially decay back to pre…
Estimate of Solar Maximum using the 1-8 ÅGeostationary Operational Environmental Satellites X-ray Measurements
L. M. Winter, K. S. Balasubramaniam
We present an alternate method of determining the progression of the solar cycle through an analysis of the solar X-ray background. Our results are based on the NOAA Geostationary…
Chromospheric mass motions and intrinsic sunspot rotations for NOAA Active Regions 10484, 10486, and 10488 using ISOON data
Paul S. Hardersen, K. S. Balasubramaniam, Svetlana Shkolyar
This work utilizes Improved Solar Observing Optical Network (ISOON: Neidig et al. 2003) continuum (630.2 nm) and Hα (656.2 nm) data to: 1) detect and measure intrinsic sunspot rota…
A failed filament eruption inside a coronal mass ejection in active region 11121
D. Kuridze, M. Mathioudakis, A. F Kowalski +4
We study the formation and evolution of a failed filament eruption observed in NOAA active region 11121 near the southeast limb on November 6, 2010. We use a time series of SDO/AIA…
Sequential Chomospheric Brightening: An Automated Approach to Extracting Physics from Ephemeral Brightening
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +2
We make a comparison between small scale chromospheric brightenings and energy release processes through examining the temporal evolution of sequential chromospheric brightenings (…
An Automated Algorithm to Distinguish and Characterize Solar Flares and Associated Sequential Chromospheric Brightenings
M. S. Kirk, K. S. Balasubramaniam, J. Jackiewicz +2
We present a new automated algorithm to identify, track, and characterize small-scale brightening associated with solar eruptive phenomena observed in Hα. The temporal spatially-lo…
