  • 5GHz TMRT observations of 71 pulsars

    We present integrated pulse profiles at 5GHz for 71 pulsars, including eight millisecond pulsars (MSPs), obtained using the Shanghai Tian Ma Radio Telescope. Mean flux densities...
  • Narrow absorption lines of lensed QSO J1029+2623

    We exploit the widely separated images of the lensed quasar SDSSJ1029+2623 (z_em_=2.197, {theta}=22.5") to observe its outflowing wind through two different sightlines. We...
  • SEAMBHs. V. The third year

    This paper reports results of the third-year campaign of monitoring super-Eddington accreting massive black holes (SEAMBHs) in active galactic nuclei (AGNs) between 2014 and...
  • The BOSS emission-line lens survey. III.

    We introduce the Baryon Oscillation Spectroscopic Survey (BOSS) Emission-Line Lens Survey GALaxy-Ly{alpha} EmitteR sYstems (BELLS GALLERY) Survey, which is a Hubble Space...
  • VLT/MUSE spectroscopic obs. of MACS J1149.5+2223

    We present Multi Unit Spectroscopic Explorer (MUSE) observations in the core of the Hubble Frontier Fields (HFF) galaxy cluster MACSJ1149.5+2223, where the first magnified and...
  • VLA, ALMA and SMA monitoring of Sgr A*

    We report new observations with the Very Large Array, Atacama Large Millimeter Array, and Submillimeter Array at frequencies from 1.0 to 355GHz of the Galactic Center black...
  • HST lensing analysis of the CLASH sample

    We present results from a comprehensive lensing analysis in Hubble Space Telescope (HST) data of the complete Cluster Lensing And Supernova survey with Hubble cluster sample...
  • HST/WFC3 observations of z~7-8 galaxies in A2744

    Exploiting the power of gravitational lensing, the Hubble Frontier Fields (HFF) program aims at observing six massive galaxy clusters to explore the distant universe far beyond...
  • HE1104-1805 BVRIJ light curves

    The gravitationally lensed quasar HE 1104-1805 has been observed at a variety of wavelengths ranging from the mid-infrared to X-ray for nearly 20yr. We combine flux ratios from...
  • Global energetics of solar flares. I.

    We present the first part of a project on the global energetics of solar flares and coronal mass ejections that includes about 400 M- and X-class flares observed with...
  • CLASH: MCS J0416.1-2403 strong lensing analysis

    We perform a strong lensing analysis of the merging galaxy cluster MACS J0416.1-2403 (M0416; z=0.42) in recent CLASH/HST observations. We identify 70 new multiple images and...
  • Rotation measures at 1.4GHz toward the LMC

    We present a study of the magnetic field of the Large Magellanic Cloud (LMC), carried out using diffuse polarized synchrotron emission data at 1.4GHz acquired at the Parkes...
  • Strong and weak lensing analysis of A2261

    We precisely constrain the inner mass profile of A2261 (z=0.225) for the first time and determine that this cluster is not "overconcentrated" as found previously, implying a...
  • Abundances in two Galactic bulge stars

    We present abundance analyses based on high dispersion and high signal-to-noise ratio Magellan spectra of two highly microlensed Galactic bulge stars in the region of the...
  • IR dust bubbles. II. YSOs model parameters

    We present an analysis of late-O/early-B-powered, parsec-sized bubbles and associated star formation using Two Micron All Sky Survey, GLIMPSE, MIPSGAL, and MAGPIS surveys. Three...
  • The Sloan lens ACS Survey. VIII.

    We study the relation between the internal structure of early-type galaxies and their environment using 70 strong gravitational lenses from the SLACS Survey. The Sloan Digital...
  • OGLE II microlensing parameters

    We present a measurement of the microlensing optical depth toward the Galactic bulge based on 4 years of the OGLE-II survey. We consider only bright sources in the extended red...
  • 4.8GHz observations of SGR 1806-20

    The 2004 December 27 giant {gamma}-ray flare detected from the magnetar SGR 1806-20 created an expanding radio nebula that we have monitored with the Australia Telescope Compact...
  • Systematic KMTNet Planetary Anomaly Search. VII.

    We present the analysis of seven microlensing planetary events with planet/host mass ratios q<10^-4^: KMT-2017-BLG-1194, KMT-2017-BLG-0428, KMT-2019-BLG-1806,...
  • Light curve of microlensing MOA-2019-BLG-008L

    We report on the observations, analysis and interpretation of the microlensing event MOA-2019-BLG-008. The observed anomaly in the photometric light curve is best described...
