Kinematic Age of the β-Pictoris Moving Group
The Astrophysical JournalAccurate age estimation of nearby young moving groups (NYMGs) is important as they serve as crucial testbeds in various fields of astrophysics, including the formation and evolution of stars and planets, as well as loose stellar associations.

The Stellar and Gaseous Kinematics in NGC 253 [PDF]
The Astrophysical Journal, 1998 This paper presents observations with intermediate spectral and spatial resolution along the major and minor axes of the starburst galaxy NGC 253. The spectral ranges analyzed are in the region of the stellar MgIb (5175 A), the near IR CaII triplet (8550 A) absorption features, and the region of the Halpha emission line.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control
Advanced Functional Materials, EarlyView.A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

The Astrophysical Journal, 2023 NGC 1052-DF4 was found to be the second “galaxy lacking dark matter” in the NGC 1052 group, based on its velocity dispersion of ${\sigma }_{\mathrm{gc}}={4.2}_{-2.2}^{+4.4}$ km s ^−1 as measured from the radial velocities of seven of its globular ...

Stellar Kinematics in Star-Forming Regions [PDF]
Symposium - International Astronomical Union, 1987 High-precision radial-velocity studies of four star-forming regions: λ Orionis, NGC 2264, the Trapezium cluster and Taurus-Auriga, are completed or in process (in collaboration with Latham, Marschall and Hartmann). Single-order (∼ 50 Å, central wavelength 5200 Å) echelle spectra have been obtained for late-type pre-main sequence stars.
