Dissecting the 3D chemo-dynamical structures of NGC~1381: A galaxy hosting an ancient slow bar with an accretion-related bulge and thick disc
Yunpeng Jin, Ling Zhu, Shude Mao +4
We applied the barred population-orbit superposition method developed in our 2025 papers to construct 3D chemo-dynamical models for the barred S0 galaxy NGC~1381 in the Fornax clus…
Kinematics of RR Lyrae stars in the Galactic bulge with OGLE-IV and Gaia DR2
Hangci Du, Shude Mao, E. Athanassoula +2
We analyze the kinematics and spatial distribution of 15,599 fundamental-mode RR Lyrae (RRL) stars in the Milky Way bulge by combining OGLE-IV photometric data and Gaia DR2 proper…
OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf
Shota Miyazaki, Takahiro Sumi, David P. Bennett +92
We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…
Rest-frame UV Properties of Luminous Strong Gravitationally Lensed Ly Emitters from the BELLS GALLERY Survey
R. Marques-Chaves, I. Pérez-Fournon, Y. Shu +15
We present deep rest-frame UV spectroscopic observations using the Gran Telescopio Canarias of six gravitationally lensed Lya emitters (LAEs) at selected from the BEL…
OGLE-2015-BLG-1649Lb: A gas giant planet around a low-mass dwarf
Masayuki Nagakane, Chien-Hsiu Lee, Naoki Koshimoto +66
We report the discovery of an exoplanet in microlensing event OGLE-2015-BLG-1649. The planet/host-star mass ratio is and the projected separation normalized…
SDSS-IV MaNGA: pattern speeds of barred galaxies
Rui Guo, Shude Mao, E. Athanassoula +5
The MaNGA project has obtained IFU data for several thousand nearby galaxies, including barred galaxies. With the two dimensional spectral and kinematic information provided by IFU…
Predictions of the WFIRST Microlensing Survey I: Bound Planet Detection Rates
Matthew T. Penny, B. Scott Gaudi, Eamonn Kerins +4
The Wide Field InfraRed Survey Telescope (WFIRST) is the next NASA astrophysics flagship mission, to follow the James Webb Space Telescope (JWST). The WFIRST mission was chosen as…
Moderate Galaxy-Galaxy Lensing
S. Mao, J. Wang, M. C. Smith
We study moderate gravitational lensing where a background galaxy is magnified substantially, but not multiply imaged, by an intervening galaxy. We focus on the case where both the…
Made-to measure galaxy models - I Methodology
R. J. Long, S. Mao
We re-derive the made-to-measure method of Syer and Tremaine 1996, for modelling stellar systems and individual galaxies, and demonstrate how extensions to the made-to-measure meth…
Photometric Properties and Scaling Relations of Early Type Brightest Cluster Galaxies
F. S. Liu, X. Y. Xia, Shude Mao +2
We investigate the photometric properties of the early type Brightest Cluster Galaxies (BCGs) using a carefully selected sample of 85 BCGs from the C4 cluster catalogue with redshi…
Acceleration and Parallax Effects in Gravitational Microlensing
M. C. Smith, S. Mao, B. Paczynski
To generate the standard microlensing light curve one assumes that the relative motion of the source, the lens, and the observer is linear. In reality, the relative motion is likel…
Optical Gravitational Lensing Experiment. OGLE-1999-BUL-19: The First Multi-Peak Parallax Event
M. C. Smith, S. Mao, P. Wozniak +6
We describe a highly unusual microlensing event, OGLE-1999-BUL-19, which exhibits multiple peaks in its light curve. The Einstein radius crossing time for this event is approximate…
Parallax Microlensing Events in the OGLE II Database Toward the Galactic Bulge
M. C. Smith, S. Mao, P. R. Wozniak
We present a systematic search for parallax microlensing events among a total of 512 microlensing candidates in the OGLE II database for the 1997-1999 seasons. We fit each microlen…
Modelling The First Probable Two Plane Lens System B2114+022: Reproducing Two Compact Radio Cores A, D
K. -H. Chae, S. Mao, P. Augusto
We test possible lensing scenarios of the JVAS system B2114+022, in which two galaxies at different redshifts (``G1'' at and ``G2'' at ) are found with…
