Breaking the Degeneracy between Warps and Radial Flows in External Galaxies

open access: yesThe Astrophysical Journal
Observations of the line-of-sight (LOS) component of emitter velocities in galaxies are valuable for reconstructing their two-dimensional (2D) velocity fields, albeit requiring certain assumptions.

Velocity Dispersion of the Open Cluster NGC 2571 by Radial Velocities and Proper Motions

open access: yesThe Astronomical Journal
We use a kernel density estimator method to evaluate the stellar velocity dispersion in the open cluster NGC 2571. We derive the 3D velocity dispersion using both proper motions as extracted from Gaia Data Release 3 and single-epoch radial velocities as ...

Extreme Long Period Eclipsing Binary Epsilon Aurigae [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1990
From the study of a spectroscopic plate of epsilon Aurigae, we can measure the radial velocity and the relative abundance for this eclipsing binary. Calculated radial velocity is -37 Km/s and the abundance of [Fe] is estimated as -1.5.

Commission 30. Radial Velocities (Vitesses Radiales) [PDF]

open access: yesTransactions of the International Astronomical Union, 1997
A new generation of major redshift surveys, with numbers of redshifts that far surpass those of earlier investigations, is getting under way. These surveys make use of fibre optics, but differ from earlier systems in that often hundreds - not just tens - of galaxies can be observed simultaneously, by means of improved fibre management techniques.

Light‐Responsive Enzyme‐Loaded Nanoparticles for Tunable Adhesion and Mechanical Wound Contraction

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a photoactivatable enzyme‐loaded mesoporous nanoparticle system (MPDA_PaTy) that enables light‐triggered tunable tissue adhesion and facilitates mechanical wound contraction. Controlled enzymatic crosslinking at tissue or hydrogel interfaces allows on‐demand adhesion.

paired: A Statistical Framework for Detecting Stellar Binarity with Gaia RVs. I. Sensitivity to Unresolved Binaries

open access: yesThe Astrophysical Journal
Data Release 3 (DR3) from the Gaia Mission includes radial velocity measurements of over 33 million targets. Among many scientific applications, the overlap of this stellar sample with targeted exoplanet transit survey stars presents an opportunity to ...
