Identifying Exoplanets and Unmasking False Positives with NGTS
… of the Next Generation Transit Survey (NGTS), a ground-based wide-field survey operating at ESO’s Paranal Observatory in Chile since 2016. My original contribution to knowledge is the development of novel methods to 1) estimate NGTS’ yield of planets and false positives; 2) disentangle …

Constraining Stellar Evolution in Young Open Clusters with NGTS
… scarce. The Next Generation Transit Survey (NGTS) is a multi-telescope, ground-based, wide-field photometric survey which is well-suited to studying these environments, and its observations are at the heart of this thesis, which presents my research in the field of early-stage stellar …

Data-driven Approaches to Stellar Variability Detection and Characterisation
… of this work has been conducted as a part of the NGTS consortium. I implemented and tested a novel generalisation of the autocorrelation function (the G-ACF), which applies to irregularly sampled data, such as photometric light curves from ground-based telescopes. I demonstrated that this …

Noble gas isotopic signatures in thermal waters of the Dead Sea Transform, Israel
… than southern ones. Noble gas temperatures (NGTs) were used to determine the atmospheric helium component. Most of the samples contain less than 3% atmospheric helium, whereas the mantle derived helium component ranges from 2% to 38%. In addition to helium, the origin of CO2 in the water is …

Unearth: Revealing the Effects of Stellar Activity on Exoplanet Host Stars
… tool was specifically de- signed to be used with NGTS light-curves. I apply the tool to a number of interesting NGTS targets with the results from each target highlighted in the relevant sections. The combined methods were able to provide more robust detections of stellar rotation periods and a …

Understand thy star, understand thy planet
… presenting the discovery of two hot Jupiters by NGTS. Following this discovery, I investigate how to detect smaller exoplanets using our best example: the Sun. Using the HARPS-N solar telescope, I study the possibility of detecting Venus using the RV method. However, finding Venus is proven to be …

NUOVE TECNICHE GENOMICHE APPLICATE AGLI AGRUMI PER L’OTTENIMENTO DI FRUTTI APIRENI
… anche note come Nuove Tecniche Genomiche (NGTs) rappresenta una valida alternativa alle tecniche tradizionali, quali l’ibridazione, la mutagenesi e la selezione, in quanto consente di introdurre modifiche precise senza alterare il background genetico originale della varietà considerata. …
