A NEW REALIZATION OF THE GLOBAL LUNAR REFERENCE FRAME BASED ON CO-REGISTERED LOLA TRACKS
Moon LOLA Reference Frame Co-Registration Polar Radius
2018/5/14
We present a method that aligns lunar south and north pole LOLA DTMs using selected LOLA tracks and co-registration techniques. The selected LOLA tracks were then co-registered to the aligned polar DT...
Frame-dragging, disk warping, jet precessing, and dipped X-ray lightcurve of Sw J1644+57
Frame-dragging disk warping jet precessing dipped X-ray lightcurve Sw J1644+57
2012/2/23
The X-ray transient source Sw J1644+57 recently discovered by Swift is believed to be triggered by tidal disruption of a star by a rapidly spinning supermassive black hole (SMBH). For such events, the...
High Frame-rate Imaging Based Photometry, Photometric Reduction of Data from Electron-multiplying Charge Coupled Devices (EMCCDs)
Instrumentation high angular resolution image processing photometric Gravitational lensing micro
2012/2/24
The EMCCD is a type of CCD that delivers fast readout times and negligible readout noise, making it an ideal detector for high frame rate applications which improve resolution, like lucky imaging or s...
Gamma Ray Bursts in the comoving frame
Gamma-ray: bursts— Radiation mechanisms: non thermal
2011/10/12
We estimate the bulk Lorentz factor Gamma_0 of 32 GRBs using the measured peak time of their afterglow light curves. We consider two possible scenarios for the estimate of Gamma_0: the case of a homog...
Application of speckle and (multi-object) multi-frame blind deconvolution techniques on imaging and imaging spectropolarimetric data
Sun: photosphere – Sun: spectropolarimeters
2011/9/27
We test the effects of reconstruction techniques on 2D data to determine the best approach. We obtained a time-series of spectropolarimetric data in the Fe I line at 630.25 nm with the Goettingen Fabr...
Constraints on the Assembly and Dynamics of Galaxies: I. Detailed Rest-frame Optical Morphologies on Kiloparsec-scale of z ~ 2 Star-forming Galaxies
galaxies evolution galaxies high-redshift galaxies kinematics and dynamics
2010/11/11
We present deep and high-resolution Hubble Space Telescope NIC2 F160W imaging at 1.6 μm of six z 2 star-forming galaxies with existing near-infrared integral field spectroscopy from SINFONI at the V...
Differential Morphology Between Rest-frame Optical and UV Emission from 1.5 < z < 3 Star-forming Galaxies

2010/12/27
We present the results of a comparative study of the rest-frame optical and rest-frame ultraviolet morphological properties of 117 star-forming galaxies (SFGs), including BX, BzK, and Lyman break gala...
