The Radcliffe Wave is oscillating.
Konietzka R, Goodman AA, Zucker C, Burkert A, Alves J, Foley M, Swiggum C, Koller M, Miret-Roig N. Konietzka R, et al. Nature. 2024 Apr;628(8006):62-65. doi: 10.1038/s41586-024-07127-3. Epub 2024 Feb 20. Nature. 2024. PMID: 38378142
Here we present evidence that the Radcliffe Wave is oscillating through the Galactic plane while also drifting radially away from the Galactic Centre. We use measurements of line-of-sight velocity(8) for (12)CO and three-dimensional velocities o …

A trail of dark-matter-free galaxies from a bullet-dwarf collision.
van Dokkum P, Shen Z, Keim MA, Trujillo-Gomez S, Danieli S, Dutta Chowdhury D, Abraham R, Conroy C, Kruijssen JMD, Nagai D, Romanowsky A. van Dokkum P, et al. Nature. 2022 May;605(7910):435-439. doi: 10.1038/s41586-022-04665-6. Epub 2022 May 18. Nature. 2022. PMID: 35585344 Free PMC article.
The gas separates from the dark matter in the collision and subsequent star formation leads to the formation of one or more dark-matter-free galaxies(12). Here we show that the present-day line-of-sight distances and radial velocities of DF2 and DF4 ar …

Multiple missiles fixed-time cooperative guidance without measuring radial velocity for maneuvering targets interception.
Zhang P, Zhang X. Zhang P, et al. ISA Trans. 2022 Jul;126:388-397. doi: 10.1016/j.isatra.2021.07.023. Epub 2021 Jul 17. ISA Trans. 2022. PMID: 34294461
For multiple missile simultaneously intercepting a maneuvering target, under the directed communication topologies between missiles, this paper designs a fixed-time cooperative guidance law based on three-dimensional guidance system. Furthermore, the radial velocity …

Tracking Black Hole Kicks from Gravitational-Wave Observations.
Calderón Bustillo J, Clark JA, Laguna P, Shoemaker D. Calderón Bustillo J, et al. Phys Rev Lett. 2018 Nov 9;121(19):191102. doi: 10.1103/PhysRevLett.121.191102. Phys Rev Lett. 2018. PMID: 30468604
As a result, the final remnant black hole acquires a characteristic velocity known as recoil velocity or gravitational kick. The symmetries of gravitational wave emission are reflected in the interactions of the gravitational wave modes emitted by the binary. In thi …

Reference wavelengths of Si ii, C ii, Fe i, and Ni ii for quasar absorption spectroscopy.
Nave G, Clear C. Nave G, et al. Mon Not R Astron Soc. 2021 Apr;502(4):10.1093/mnras/staa3990. doi: 10.1093/mnras/staa3990. Mon Not R Astron Soc. 2021. PMID: 34815587 Free PMC article.
Wavelengths of absorption lines in the spectra of galaxies along the line of sight to distant quasars can be used to probe the variablility of the fine structure constant, alpha, at high redshifts, provided that the laboratory wavelengths are known to better than 6 …

Method for measuring Doppler shifts in arc-heated flows.
Aeschliman DP, Hill RA. Aeschliman DP, et al. Appl Opt. 1972 Jan 1;11(1):148-52. doi: 10.1364/AO.11.000148. Appl Opt. 1972. PMID: 20111470
The wavelength difference between the blue-and red-shifted line profiles is exactly twice the Doppler shift integrated along a line of sight through the flow and is independent of a Stark shift. The Stark shift is given by the wavelength difference between th …

Helium line ratio spectroscopy for high spatiotemporal resolution plasma edge profile measurements at ASDEX Upgrade (invited).
Griener M, Wolfrum E, Cavedon M, Dux R, Rohde V, Sochor M, Muñoz Burgos JM, Schmitz O, Stroth U; ASDEX Upgrade Team. Griener M, et al. Rev Sci Instrum. 2018 Oct;89(10):10D102. doi: 10.1063/1.5034446. Rev Sci Instrum. 2018. PMID: 30399953
The diagnostic now offers a temporal resolution of 900 kHz with a spatial resolution of up to 3 mm at 32 lines of sight (LOS) simultaneously. The LOS covers a radial region of 8.5 cm, starting at the limiter radius and reaching into the confined region beyond the se …

High-resolution ultrasonic imaging of blood flow in the anterior segment of the eye.
Silverman RH, Kruse DE, Coleman DJ, Ferrara KW. Silverman RH, et al. Invest Ophthalmol Vis Sci. 1999 Jun;40(7):1373-81. Invest Ophthalmol Vis Sci. 1999. PMID: 10359319
Pulsatility over the cardiac cycle was evaluated by sending a series of pulses along a single line of sight containing a vessel of interest. Local blood flow and changes over the cardiac cycle before and after application of atropine were quantified. RESULTS: Flow w …
