Mid-Infrared Imaging of Habitable-Zone Exoplanets with LBTI

, 2022
In the next decades, ground-based direct imaging capabilities at mid-infrared wavelengths will be needed alongside JWST in order to image planets close to their stars including most nearby habitable-zone planets. The ESO/Breakthrough-sponsored New Earths in the Alpha Centauri Region (NEAR) program on the VLT recently completed the first ultra-deep ...

The TRENDS High-Contrast Imaging Survey. VII. Discovery of a Nearby Sirius-like White Dwarf System (HD 169889) [PDF]

, 2018
Monitoring the long-term radial velocity (RV) and acceleration of nearby stars has proven an effective method for directly detecting binary and substellar companions.

Forecasting water vapour above the sites of ESO's Very Large Telescope (VLT) and the Large Binocular Telescope (LBT) [PDF]

, 2018
Water vapour in the atmosphere is the main source of the atmospheric opacity in the infrared and sub-millimetric regimes and its value plays a critical role in observations done with instruments working at these wavelengths on ground-based telescopes ...

Controversies in the pathophysiology of leg ulcers in sickle cell disease

British Journal of Haematology, Volume 205, Issue 1, Page 61-70, July 2024.
Sickle leg ulcer starts as arterial due to sickling, microvascular occlusion and local hypoxia. Once the ulcer is present, venostasis and impaired angiogenesis delay healing. Summary Patients with sickle cell disease (SCD) often experience painful vaso‐occlusive crises and chronic haemolytic anaemia, as well as various acute and chronic complications ...

On-sky single-mode fiber coupling measurements at the Large Binocular Telescope

, 2016
The demonstration of efficient single-mode fiber (SMF) coupling is a key requirement for the development of a compact, ultra-precise radial velocity (RV) spectrograph.

Observation of Io's Resurfacing via Plume Deposition Using Ground‐Based Adaptive Optics at Visible Wavelengths With LBT SHARK‐VIS

Geophysical Research Letters, Volume 51, Issue 11, 16 June 2024.
Abstract Since volcanic activity was first discovered on Io from Voyager images in 1979, changes on Io's surface have been monitored from both spacecraft and ground‐based telescopes. Here, we present the highest spatial resolution images of Io ever obtained from a ground‐based telescope.

Enabling the direct detection of earth-sized exoplanets with the LBTI HOSTS project: a progress report [PDF]

SPIE Proceedings, 2016
NASA has funded a project called the Hunt for Observable Signatures of Terrestrial Systems (HOSTS) to survey nearby solar type stars to determine the amount of warm zodiacal dust in their habitable zones. The goal is not only to determine the luminosity distribution function but also to know which individual stars have the least amount of zodiacal dust.
