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

Astronomy & 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 κ 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]

Ground-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 $1-5\,μ$m imaging camera for the Large Binocular Telescope, capable of observing astronomical objects in the thermal infrared (

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 ...

High Spatial Resolution Thermal-Infrared Spectroscopy with ALES: Resolved Spectra of the Benchmark Brown Dwarf Binary HD 130948BC

, 2019
We present 2.9-4.1 micron integral field spectroscopy of the L4+L4 brown dwarf binary HD 130948BC, obtained with the Arizona Lenslets for Exoplanet Spectroscopy (ALES) mode of the Large Binocular Telescope Interferometer (LBTI). The HD 130948 system is a

ELT Imaging of MWC 297 from the 23 m LBTI: Complex Disk Structure and a Companion Candidate

The Astronomical Journal, 2020
Abstract Herbig Ae/Be stars represent the early outcomes of star formation and the initial stages of planet formation at intermediate stellar masses. Understanding both of these processes requires detailed characterization of their disk structures and companion frequencies. We present new 3.7 μm imaging of the Herbig Be star MWC 297 from

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.

High Contrast Imaging in the Visible: First Experimental Results at the Large Binocular Telescope

, 2016
In February 2014, the SHARK-VIS (System for High contrast And coronography from R to K at VISual bands) Forerunner, a high contrast experimental imager operating at visible wavelengths, was installed at LBT (Large Binocular Telescope).

Inhibitors of BMP‐1/tolloid‐like proteinases: efficacy, selectivity and cellular toxicity

FEBS Open Bio, 2018
BMP‐1/tolloid‐like proteinases belong to the astacin family of human metalloproteinases, together with meprins and ovastacin. They represent promising targets to treat or prevent a wide range of diseases such as fibrotic disorders or cancer. However, the
