The Power of High-precision Broadband Photometry: Tracing the Milky Way Density Profile with Blue Horizontal Branch Stars in the Dark Energy Survey

open access: yesThe Astrophysical Journal
Blue horizontal branch stars (BHBs), excellent distant tracers for probing the Milky Way’s halo density profile, are distinguished in the ${\left(g-r\right)}_{0}$ versus ( i − z ) _0 color space from another class of stars, blue straggler stars.

A prototype submersible sheathless flow cytometer designed for autonomous platforms

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Development of submersible flow cytometers has allowed for continuous, in situ measurements of natural assemblages of phytoplankton cells. Here we introduce DeepCyte, a sensitive prototype submersible flow cytometer developed for deployment on autonomous platforms.

Once a Triple, Not Always a Triple: The Evolution of Hierarchical Triples That Yield Merged Inner Binaries

open access: yesThe Astrophysical Journal
More than half of all main-sequence (MS) stars have one or more companions, and many of those with initial masses 10 yr) companions. Furthermore, both BSS binaries and DWDs exhibit signatures of WD birth kicks.

Blue straggler populations beyond the Milky Way

open access: yesCommunications of the Byurakan Astrophysical Observatory, 2018
Although the formation of blue straggler stars (BSSs) is routinely attributed to stellar interactions in binary systems, the relative importance of the direct collision and slow(er) stellar coalescence formation channels is still poorly understood. We selected a sample of 24 Magellanic Cloud star clusters for which multi-passband Hubble Space Telescope

Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems

open access: yesLaser &Photonics Reviews, EarlyView.
This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...

Metasurfaces in Adaptive Optics: A New Opportunity in Optical Wavefront Sensing

open access: yesLaser &Photonics Reviews, EarlyView.
Wavefront sensing constitutes a critical component of adaptive optics systems, aimed at quantitatively measuring distorted wavefronts and enabling closed‐loop correction in optical setups. Metasurfaces, as planar optical elements composed of nanoscale structures, provide exceptional freedom in modulating multiple dimensions of the light field.

The Impact of Stellar Rotations and Binaries on the Shape of Upper Main Sequence near Turnoff in Open Cluster NGC 6067

open access: yesThe Astrophysical Journal
We present the analysis of the extended main-sequence turnoff (eMSTO) in the open cluster NGC 6067. We derive the projected rotational velocity, v sin i , of the stars belonging to the eMSTO region of the main sequence (MS) utilizing Gaia-ESO spectra ...
