Hubble's Wide Field Camera 3 (WFC3) is the workhorse instrument for HST, providing direct (staring) and scanning modes using filters and grisms, covering from...
Macroturbulent broadening and its consequences on the study of rotational velocities and pulsations in massive stars
The analysis of high-resolution spectra of blue massive stars has allowed us to firmly ascertain the presence of an important non-rotational broadening in O and...
Macroturbulent broadening in Massive Stars and its possible connection to Stellar Oscillations
In this contribution, I review what we have learnt about macroturbulent broadening in the last decade and present first results of a long term observational...
MAD@VLT: Deep into the Madding Crowd of Omega Centauri
We present deep and accurate Near-Infrared (NIR) photometry of the Galactic Globular Cluster (GC) ω Cen. Data were collected using the Multi-Conjugate Adaptive...
Mag Waves in Sunspot Umbra: Slow Mode Leaking to the Corona
The linear oscillations of a stratified atmosphere embedded by a uniform vertical magnetic field are studied here. We use a simple theoretical model formed by...
Magellanic Cloud Emission Line Survey, Spectroscopy analisis
This work presents a low resolution spectroscopic data analisis of HII regions in the magellanic clouds. Nineteen nights of data over five observing seasons...
Magellanic Cloud Planetary Nebulae: probing the effects of metallicity on dust formation, mass-loss, and evolution.
Planetary nebulae (PNe) in the Magellanic Clouds (LMC, SMC) offer a unique opportunity to study both the population and evolution of low- and intermediate-mass...
MAGIC detection of sub-TEV emission from gravitationally lensed blazar QSO B0218+357
The blazar QSO B0218+357 is the first gravitationally lensed blazar detected in the very high energy (VHE, E > 100 GeV) gamma-ray spectral range (Ahnen et al...
