We present the analysis of three more planets from the KMTNet 2021 microlensing season. KMT-2021-BLG-0119Lb is a ~6M Jup planet orbiting an early M dwarf or a K dwarf, KMT-2021-BLG-0192Lb is a ~2M Nep planet orbiting an M dwarf, and KMT-2021-BLG-2294Lb is a ~1.25M Nep planet orbiting a very-low-mass M dwarf or a brown dwarf. These by-eye planet

We apply a statistical deconvolution of the parallax errors based on Lucy's inversion method (LIM) to the Gaia DR3 sources to measure their 3D velocity components in the range of Galactocentric distances R between 8 and 30 kpc with their corresponding errors and rms values. We find results that are consistent with those obtained by applying LIM to

Hubble's Wide Field Camera 3 (WFC3) is the workhorse instrument for HST, providing direct (staring) and scanning modes using filters and grisms, covering from the near-IR to near-UV. Installed during the most recent HST servicing mission in 2009, WFC3 has logged almost 300,000 observations resulting in exciting scientific discoveries over the past

The bulk of stellar and black hole mass buildup in galaxies occurs in the high-redshift Universe in short, intense bursts of star formation and black hole accretion. However, the exact role of these two processes in assembling galaxies, as well as how much they affect one another, remains unclear. It is thus important to create case studies of high

The classical globular clusters found in all galaxy types have half-light radii of r h ~ 2-4 pc, which have been tied to formation in the dense cores of giant molecular clouds. Some old star clusters have larger sizes, and it is unclear if these represent a fundamentally different mode of low-density star cluster formation. We report the discovery
