Damping of optomechanical disks resonators vibrating in air
D. Parrain, C. Baker, T. Verdier +5
We report on miniature GaAs disk optomechanical resonators vibrating in air in the radiofrequency range. The flexural modes of the disks are studied by scanning electron microscopy…
Laser cooling and control of excitations in superfluid helium
G. I. Harris, D. L. McAuslan, E. Sheridan +3
Superfluidity is an emergent quantum phenomenon which arises due to strong interactions between elementary excitations in liquid helium. These excitations have been probed with gre…
High frequency nano-optomechanical disk resonators in liquids
E. Gil-Santos, C. Baker, D. T. Nguyen +5
Vibrating nano- and micromechanical resonators have been the subject of research aiming at ultrasensitive mass sensors for mass spectrometry, chemical analysis and biomedical diagn…
WFIRST-2.4: What Every Astronomer Should Know
D. Spergel, N. Gehrels, J. Breckinridge +43
The Astro2010 Decadal Survey recommended a Wide Field Infrared Survey Telescope (WFIRST) as its top priority for a new large space mission. The report of the WFIRST-AFTA Science De…
Predicting Gravitational Lensing by Stellar Remnants
A. J. Harding, R. Di Stefano, S. Lépine +3
Gravitational lensing provides a means to measure mass that does not rely on detecting and analysing light from the lens itself. Compact objects are ideal gravitational lenses, bec…
ANDES, the high resolution spectrograph for the ELT: science goals, project overview and future developments
A. Marconi, M. Abreu, V. Adibekyan +286
The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…
A small actively-controlled high-resolution spectrograph based on off-the-shelf components
H. R. A. Jones, W. E. Martin, G. Anglada-Escudé +5
We present the design and testing of a prototype in-plane echelle spectrograph based on an actively controlled fibre-fed double-pass design. This system aims to be small and effici…
Microphotonic Forces From Superfluid Flow
D. L. McAuslan, G. I. Harris, C. Baker +4
In cavity optomechanics, radiation pressure and photothermal forces are widely utilized to cool and control micromechanical motion, with applications ranging from precision sensing…
Critical optical coupling between a GaAs disk and a nanowaveguide suspended on the chip
C. Baker, C. Belacel, A. Andronico +6
We report on an integrated GaAs disk/waveguide system. A millimeter-long waveguide is suspended and tapered on the chip over a length of 25 μm to evanescently couple to high Q opt…
Wide-Field InfraRed Survey Telescope-Astrophysics Focused Telescope Assets WFIRST-AFTA Final Report
D. Spergel, N. Gehrels, J. Breckinridge +43
The Astro2010 Decadal Survey recommended a Wide Field Infrared Survey Telescope (WFIRST) as its top priority for a new large space mission. As conceived by the decadal survey, WFIR…
