MAIRA-1: A specialised large multimodal model for radiology report generation
Stephanie L. Hyland, Shruthi Bannur, Kenza Bouzid +12
We present a radiology-specific multimodal model for the task for generating radiological reports from chest X-rays (CXRs). Our work builds on the idea that large language model(s)…
Exploring the Limits of Synthetic Creation of Solar EUV Images via Image-to-Image Translation
Valentina Salvatelli, Luiz F. G. dos Santos, Souvik Bose +6
The Solar Dynamics Observatory (SDO), a NASA multi-spectral decade-long mission that has been daily producing terabytes of observational data from the Sun, has been recently used a…
Unsupervised Change Detection of Extreme Events Using ML On-Board
Vít Růžička, Anna Vaughan, Daniele De Martini +5
In this paper, we introduce RaVAEn, a lightweight, unsupervised approach for change detection in satellite data based on Variational Auto-Encoders (VAEs) with the specific purpose…
Multi-Channel Auto-Calibration for the Atmospheric Imaging Assembly using Machine Learning
Luiz F. G. dos Santos, Souvik Bose, Valentina Salvatelli +7
Solar activity plays a quintessential role in influencing the interplanetary medium and space-weather around the Earth. Remote sensing instruments onboard heliophysics space missio…
Auto-Calibration of Remote Sensing Solar Telescopes with Deep Learning
Brad Neuberg, Souvik Bose, Valentina Salvatelli +6
As a part of NASA's Heliophysics System Observatory (HSO) fleet of satellites,the Solar Dynamics Observatory (SDO) has continuously monitored the Sun since2010. Ultraviolet (UV) an…
Using U-Nets to Create High-Fidelity Virtual Observations of the Solar Corona
Valentina Salvatelli, Souvik Bose, Brad Neuberg +6
Understanding and monitoring the complex and dynamic processes of the Sun is important for a number of human activities on Earth and in space. For this reason, NASA's Solar Dynamic…
Power law cosmology model comparison with CMB scale information
Isaac Tutusaus, Brahim Lamine, Alain Blanchard +14
Despite the ability of the cosmological concordance model (CDM) to describe the cosmological observations exceedingly well, power law expansion of the Universe scale radius, $R(…
Constraints on modified gravity from Planck 2015: when the health of your theory makes the difference
Valentina Salvatelli, Federico Piazza, Christian Marinoni
We use the effective field theory of dark energy (EFT of DE) formalism to constrain dark energy models belonging to the Horndeski class with the recent Planck 2015 CMB data. The sp…
Planck 2015 results. XIV. Dark energy and modified gravity
Planck Collaboration, P. A. R. Ade, N. Aghanim +232
We study the implications of Planck data for models of dark energy (DE) and modified gravity (MG), beyond the cosmological constant scenario. We start with cases where the DE only…
Indications of a late-time interaction in the dark sector
Valentina Salvatelli, Najla Said, Marco Bruni +2
We show that a general late-time interaction between cold dark matter and vacuum energy is favoured by current cosmological datasets. We characterize the strength of the coupling b…
Far-infrared Fine-Structure Line Diagnostics of Ultraluminous Infrared Galaxies
Duncan Farrah, Vianney Lebouteiller, Henrik Spoon +16
We present Herschel observations of six fine-structure lines in 25 Ultraluminous Infrared Galaxies at z<0.27. The lines, [O III]52, [N III]57, [O I]63, [N II]122, [O I]145, and [C…
Updated constraints from the PLANCK experiment on modified gravity
Andrea Marchini, Valentina Salvatelli
A modification of the action of the general relativity produces a different pattern for the growth of the cosmic structures below a certain length-scale leaving an imprint on the c…
New constraints on Coupled Dark Energy from Planck
Valentina Salvatelli, Andrea Marchini, Laura Lopez-Honorez +1
We present new constraints on coupled dark energy from the recent measurements of the Cosmic Microwave Background Anisotropies from the Planck satellite mission. We found that a co…
Constraints on Modified Gravity from ACT and SPT
Andrea Marchini, Alessandro Melchiorri, Valentina Salvatelli +1
The Atacama Cosmology Telescope (ACT) and the South Pole Telescope (SPT) have recently provided new and precise measurements of the Cosmic Microwave Background anisotropy damping t…
Parametrised modified gravity and the CMB Bispectrum
Eleonora Di Valentino, Alessandro Melchiorri, Valentina Salvatelli +1
We forecast the constraints on modified theories of gravity from the cosmic microwave background (CMB) anisotropies bispectrum that arises from correlations between lensing and the…
Future constraints on the Hu-Sawicki modified gravity scenario
Matteo Martinelli, Alessandro Melchiorri, Olga Mena +2
We present current and future constraints on the Hu and Sawicki modified gravity scenario. This model can reproduce a late time accelerated universe and evade solar system constrai…
