Simulation of soft X-ray emission lines from the missing baryons
theory diff use radiation large-scale structure of universe
2014/12/24
We study the soft X-ray emission (0.1-1 keV) from the warm-hot intergalactic medium (WHIM) in a hydrodynamic simulation of a cold dark matter universe. Our main goal is to investigate how such emissio...

Emissions Molecular cloud Emissions High resolution Echelle spectrum The center of mass velocity
2014/12/9
Results are presented for the He emission in 31 CTTS from the Taurus-Auriga molecular cloud spanning two orders of magnitude in the mass accretion rate, and for the Fe emission in DR Tau, based on a s...
First observations of CN(2-1), HCO$^{+}$(3-2) and C$_{2}$H(3-2) emission lines in the Perseus cluster: constraints on heating mechanisms in the cluster gas

2011/10/8
We present the first observations of emission lines of CN(2-1), HCO$^{+}$(3-2) and C$_{2}$H(3-2) in the Perseus cluster. We observed at two positions: directly at the central galaxy, NGC 1275 and also...
Strong [O III] and [N II] emission lines in globular clusters from photoionized R Corona Borealis star winds
emission lines globular clusters
2011/1/13
The globular cluster X-ray source CXO J033831.8-352604 in NGC 1399 has recently been found to show strong emission lines of [O III] and [N II] in its optical spectrum in addition to ultraluminous X-ra...
Probing Intermediate Mass Black Holes With Optical Emission Lines from Tidally Disrupted White Dwarfs
Probing Intermediate Mass Black Holes Optical Emission Lines
2011/1/13
We calculate the emission line spectrum produced by the debris released when a white dwarf (WD) is tidally disrupted by an intermediate-mass black hole (IMBH; $M\sim 10^{2}-10^{5}\msun$) and we explor...
Spectroscopic Studies of Solar Corona VI: Trend in Line-width Variation of Coronal Emission Lines with Height Independent of the Structure of Coronal Loops
Sun corona coronal structures emission line widt techniques spectroscopy
2010/9/16
We have obtained spectroscopic observations in coronal emission lines by choosing two lines simultaneously, one [Fe x] 6374Å and the other [Fe xi] 7892Å or [Fe xiii] 10747Å or [Fe xi...
