Positive and negative feedback of AGN outflows in NGC 5728
Jaejin Shin, Jong-Hak Woo, Aeree Chung +4
We present a spatially-resolved analysis of ionized and molecular gas in a nearby Seyfert 2 galaxy NGC 5728, using the VLT/MUSE and ALMA data. We find ionized gas outflows out to ~…
The Observational Evidence for the Internal Excitation of Sunspot Oscillations Inferred from the Fe I 5435 A Line
Kyuhyoun Cho, Jongchul Chae, Eun-kyung Lim +1
The umbral oscillations of velocity are commonly observed in the chromosphere of a sunspot. Their sources are considered to be either the external p-mode driving or the internal ex…
The Physical Nature of Spiral Wave Patterns in Sunspots
Juhyung Kang, Jongchul Chae, Valery M. Nakariakov +3
Recently, spiral wave patterns (SWPs) have been detected in 3 minute oscillations of sunspot umbrae, but the nature of this phenomenon has remained elusive. We present a theoretica…
