Latent tuberculosis infection in health-care workers in the government sector in Brunei Darussalam: A cross-sectional study

open access: yesJournal of Integrative Nursing, 2023
Objective: Health-care workers (HCWs) are known to be at high risk for occupational biological hazards, and this includes exposure to mycobacterium tuberculosis (TB) which can result in either active or latent TB infection (LTBI).

Warm exo-Zodi from cool exo-Kuiper belts: The significance of P-R drag and the inference of intervening planets [PDF]

open access: yes, 2015
Poynting-Robertson drag has been considered an ineffective mechanism for delivering dust to regions interior to the cool Kuiper belt analogues seen around other Sun-like stars.

Characterization of the gaseous companion �� Andromedae b: New Keck and LBTI high-contrast observations [PDF]

open access: yesAstronomy & Astrophysics, 2013
We previously reported the direct detection of a low mass companion at a projected separation of 55+-2 AU around the B9 type star Andromedae. The properties of the system (mass ratio, separation) make it a benchmark for the understanding of the formation and evolution of gas giant planets and brown dwarfs on wide-orbits.

MEAD: data reduction pipeline for ALES integral field spectrograph and LBTI thermal infrared calibration unit [PDF]

open access: yesGround-based and Airborne Instrumentation for Astronomy VII, 2018
We present the data reduction pipeline, MEAD, for Arizona Lenslets for Exoplanet Spectroscopy (ALES), the first thermal infrared integral field spectrograph designed for high-contrast imaging. ALES is an upgrade of LMIRCam, the $1-5\, $m imaging camera for the Large Binocular Telescope, capable of observing astronomical objects in the thermal infrared

Delay Compensation for Real Time Disturbance Estimation at Extremely Large Telescopes [PDF]

open access: yes, 2016
In ground-based astronomy, aberrations due to structural vibrations, such as piston, limit the achievable resolution and cannot be corrected using adaptive optics (AO) for large telescopes.

Towards controlled Fizeau observations with the Large Binocular Telescope

open access: yes, 2018
The Large Binocular Telescope Interferometer (LBTI) can perform Fizeau interferometry in the focal plane, which accesses spatial information out to the LBT's full 22.7-m edge-to-edge baseline.

First Light with ALES: A 2-5 Micron Adaptive Optics Integral Field Spectrograph for the LBT

open access: yes, 2015
Integral field spectrographs are an important technology for exoplanet imaging, due to their ability to take spectra in a high-contrast environment, and improve planet detection sensitivity through spectral differential imaging.

SFADI: the Speckle-Free Angular Differential Imaging method [PDF]

open access: yes, 2017
We present a new processing technique aimed at significantly improving the angular differential imaging method (ADI) in the context of high-contrast imaging of faint objects nearby bright stars in observations obtained with extreme adaptive optics (EXAO)
