Classifying Astronomical Transients Using Only Host Galaxy Photometry
Marina Kisley, Yu-Jing Qin, Ann Zabludoff +2
The Legacy Survey of Space and Time (LSST) at the Vera C. Rubin Observatory will discover tens of thousands of extragalactic transients each night. The high volume of alerts demand…
Possible Ongoing Merger Discovered by Photometry and Spectroscopy in the Field of the Galaxy Cluster PLCK G165.7+67.0
Massimo Pascale, Brenda L. Frye, Liang Dai +17
We present a detailed study of the Planck-selected binary galaxy cluster PLCK G165.7+67.0 (G165; =0.348). A multiband photometric catalog is generated that incorporates new imag…
Deprojection of external barred galaxies from photometry
Behzad Tahmasebzadeh, Ling Zhu, Juntai Shen +2
The observations of external galaxies are projected to the 2D sky plane. Reconstructing the 3D intrinsic density distribution of a galaxy from the 2D image is challenging, especial…
An Empirical Proxy for the Second Integral of Motion in Rotating Barred or Tri-axial Potentials
Yu-Jing Qin, Juntai Shen
We identify an effective proxy for the analytically-unknown second integral of motion (I_2) for rotating barred or tri-axial potentials. Planar orbits of a given energy follow a ti…
Distinguishing Tidal Disruption Events from Impostors
Ann Zabludoff, Iair Arcavi, Stephanie La Massa +15
Recent claimed detections of tidal disruption events (TDEs) in multi-wavelength data have opened potential new windows into the evolution and properties of otherwise dormant superm…
PLCK G165.7+67.0: Analysis of a Massive Lensing Cluster in a Hubble Space Telescope Census of Submillimeter Giant Arcs Selected Using Planck/Herschel
Brenda L. Frye, Massimo Pascale, Yujing Qin +19
We present Hubble Space Telescope WFC3-IR imaging in the fields of six apparently bright dusty star-forming galaxies (DSFGs) at = 2-4 identified by their rest-frame far-infrare…
The local spiral arm in the LAMOST-Gaia common stars?
Chao Liu, You-Gang Wang, Juntai Shen +7
Using the LAMOST-Gaia common stars, we demonstrate that the in-plane velocity field for the nearby young stars are significantly different from that for the old ones. For the young…
Kinematics of the X-shaped Milky Way Bulge: Expectations from a Self-consistent N-body Model
Yujing Qin, Juntai Shen, Zhao-Yu Li +5
We explore the kinematics (both the radial velocity and the proper motion) of the vertical X-shaped feature in the Milky Way with an N-body bar/bulge model. From the solar perspect…
A Vertical Resonance Heating Model for X- or Peanut-Shaped Galactic Bulges
Alice C. Quillen, Ivan Minchev, Sanjib Sharma +2
We explore a second order Hamiltonian vertical resonance model for X-shaped or peanut-shaped galactic bulges. The X-shape is caused by the 2:1 vertical Lindblad resonance with the…
