Stars made in outflows may populate the stellar halo of the Milky Way
Sijie Yu, James S. Bullock, Andrew Wetzel +8
We study stellar-halo formation using six Milky Way-mass galaxies in FIRE-2 cosmological zoom simulations. We find that of the outer ( kpc) stellar halo in each sy…
X-shaped Radio Galaxies: Optical Properties, Large-scale Environment and Relationship to Radio Structure
Ravi Joshi, Gopal-Krishna, Xiaolong Yang +9
In order to find clues to the origin of the "winged" or "X-shaped" radio galaxies (XRGs) we investigate here the parent galaxies of a large sample of 106 XRGs for optical-radio axe…
On the Source Position and Duration of a Solar Type III Radio Burst Observed by LOFAR
PeiJin Zhang, SiJie Yu, Eduard Kontar +1
Solar type III radio bursts are excited by electron beams propagating outward from the Sun. The flux of type III radio burst has a time profile of rising and decay phase at a given…
A Tight Relation between Spiral Arm Pitch Angle and Protoplanetary Disk Mass
Si-Yue Yu, Luis C. Ho, Zhaohuan Zhu
We use two-dimensional Fourier transformation to measure the pitch angle () of the dominant spiral Fourier mode of well-defined spiral arms in 13 protoplanetary disks, making us…
Possible Detection of Subsecond-period Propagating Magnetohydrodynamics Waves in Post-reconnection Magnetic Loops during a Two-ribbon Solar Flare
Sijie Yu, Bin Chen
Solar flares involve the sudden release of magnetic energy in the solar corona. Accelerated nonthermal electrons have often been invoked as the primary means for transporting the b…
