OGLE, KMTNet & Spitzer EWS2017-BLG-1038 light curve
We report the analysis of microlensing event OGLE-2017-BLG-1038, observed by the Optical Gravitational Lensing Experiment, Korean Microlensing Telescope Network, and Spitzer... -
VRI light curve of MOA 2020-BLG-135
We report the light-curve analysis for the event MOA-2020-BLG-135, which leads to the discovery of a new Neptune-class planet, MOA-2020-BLG-135Lb. With a derived mass ratio of... -
Mass Production 2021 KMTNet Microlensing Planets. I.
We inaugurate a program of "mass production" of microlensing planets discovered in 2021 KMTNet data, with the aim of laying the basis for future statistical studies. While we... -
Spectroscopy in lens fields
We present the first results from our spectroscopic survey of strong gravitational lens environments. Six of the eight lens galaxies in our sample belong to a poor group of... -
Disk mass loss in the Orion Nebula Cluster
The relevance of encounters on the destruction of protoplanetary disks in the Orion Nebula cluster (ONC) is investigated by combining two different types of numerical... -
VLA rotation measures in the Galactic plane
We have determined 194 Faraday rotation measures (RMs) of polarized extragalactic radio sources using new, multi-channel polarization observations at frequencies around 1.4GHz... -
Accretion rate of AGNs from COSMOS surveys
We show how accretion rate governs the physical properties of a sample of unobscured broad-line, narrow-line, and lineless active galactic nuclei (AGNs). We avoid the systematic... -
SEAMBHs. II. Continuum and Hbeta LCs
This is the second in a series of papers reporting on a large reverberation mapping (RM) campaign to measure black hole (BH) mass in high accretion rate active galactic nuclei... -
Spitzer/IRAC Sgr A* light curve data
We present the first detection from the Spitzer Space Telescope of 4.5 {mu}m variability from Sgr A, the emitting source associated with the Milky Way's central black hole. The... -
Polar network index for the solar cycle studies
The Sun has a polar magnetic field which oscillates with the 11 yr sunspot cycle. This polar magnetic field is an important component of the dynamo process which operates in the... -
Polarization and photometry for blazar W Comae
An R-band photopolarimetric variability analysis of the TeV bright blazar W Comae between 2008 February 28 and 2013 May 17 is presented. The source showed a gradual tendency to... -
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... -
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... -
Microlensing optical depth & event rates from MOA-II
We find that significant incompleteness in stellar number counts results in a significant overestimate of the microlensing optical depth {tau} and event rate per star per year... -
Spectral analysis of low-mass X-ray binaries
A recent study of a small sample of X-ray binaries (XRBs) suggests a significant softening of spectra of neutron star (NS) binaries as compared to black hole (BH) binaries in... -
MEGaSaURA. II. Stacked spectra
We stack the rest-frame ultraviolet spectra of N=14 highly magnified gravitationally lensed galaxies at redshifts 1.6<z<3.6. The resulting new composite spans... -
Opt. follow-up of galaxies within S190814bv region
On 2019 August 14 the Laser Interferometer Gravitational Wave Observatory (LIGO) and the Virgo gravitational wave interferometer announced the detection of a binary merger,... -
Global energetics of solar flares. IX.
A more accurate analytical solution of the vertical-current approximation nonlinear force-free field (VCA3-NLFFF) model is presented that includes, besides the radial (Br) and... -
Starspots's temperature and area in 337 KIC stars
Upcoming missions, including the James Webb Space Telescope, will soon characterize the atmospheres of terrestrial-type exoplanets in habitable zones around cool K- and M-type...
