PublicationA Search for the Optical Counterpart to the Magnetar CXOU J010043.1-721134
After our tentative detection of an optical counterpart to CXOU J010043.1-721134 from archival Hubble Space Telescope (HST) imaging, we have followed up with...

PublicationA Search for Very Low Mass Stars and Brown Dwarfs in the Young sigma Orionis Cluster
We present a CCD-based photometric survey covering 870 arcmin^2 in a young stellar cluster around the young multiple star sigma Orionis. Our survey-limiting R...

PublicationA Second-order Moment of Microlensing Variability as a Novel Tool to Constrain Source Emission Size or Discrete Lens Demographics in Extragalactic Research
We define a second-order moment of the observational differential microlensing curves that can be used to impose constraints on physical properties of lensed...

PublicationA Shallow Dark Matter Halo in Ultra-diffuse Galaxy AGC 242019: Are UDGs Structurally Similar to Low-surface-brightness Galaxies?
A central question regarding ultra-diffuse galaxies (UDGs) is whether they are in a separate category from low-surface-brightness (LSB) galaxies, or just their...

PublicationA Simple Model for the Distribution of Quiet-Sun Magnetic Field Strengths
We derive a first-order linear differential equation describing the shape of the probability density function (PDF) of magnetic field strengths in the quiet Sun...

PublicationA Simple Procedure for Optimizing the Height Resolution in Spectral Line Inversions
This paper presents a method to determine how much detail of the height stratification of atmospheric parameters can be retrieved from the inversion of spectral...
