Trosolwyg
Rwy'n ymwneud â datblygu cenadaethau ac arsyllfeydd ar gyfer nodweddu atmosfferau allblanedol. Rwy'n ymwneud yn fawr â datblygu taith ofod ESA Ariel a chenhadaeth EXCITE NASA.
Rwyf hefyd yn arloesi rhai astudiaethau poblogaethau allblanedol gyda chydweithrediad cryf â sefydliadau cenedlaethol a rhyngwladol, megis UCL, JPL, "Sapienza" Prifysgol Rhufain, INAF, ac ati.
Mae fy ngweithgareddau hefyd yn cynnwys allgymorth, gan fy mod yn arwain prosiectau sydd wedi'u hanelu at fyfyrwyr ysgol uwchradd a rhaglenni gwyddonwyr dinasyddion i gynnwys seryddwyr amatur.

Ymchwil
Mae fy mhrif ddiddordebau ymchwil ym maes nodweddu ecsoblaned. Gan fod exoplanets yn anodd eu hastudio gyda'n technoleg gyfredol, rwy'n canolbwyntio fy ymdrechion ar ddatblygu dulliau rhifiadol newydd ar gyfer dadansoddi data ac optimeiddio offer. Dros y blynyddoedd rwyf wedi ennill profiad o ddatblygu a defnyddio gwahanol offer a thechnegau, gan gynnwys adalw atmosfferig, efelychwyr offeryn o'r dechrau i'r diwedd, graddnodi offerynnau, a phiblinellau sy'n tueddu data.
Cenadaethau ecsoblanedol
- ARIEL - Cydlynydd Gweithgorau. Datblygu a chynnal a chadw'r offer efelychu a'r biblinell lleihau data. Efelychu perfformiad cenhadaeth a dadansoddi data.
- EXCITE - perfformiad cenhadaeth a dadansoddi data
Poblogaethau planedol
Yn ystod y degawd diwethaf, mae nifer yr exoplanets hysbys wedi cynyddu ddeg gwaith: ar ddiwedd 2009, roedd tua 400 o exoplanets hysbys, tra ar ddiwedd 2019, cyrhaeddodd darganfyddiadau wedi'u cadarnhau fwy na 4000. Mae'r nifer hwn yn dal i gynyddu, diolch i ofod a chenadaethau ar y ddaear, a chyda hynny, mae ein dealltwriaeth o ecsoblanedau yn newid. Dechreuais ddatblygu offer ystadegol i nodweddu a dosbarthu nid yn unig planedau unigol, ond poblogaethau cyfan.
Meddalwedd a ddatblygwyd
Efelychwyr rhifiadol yn offer sylfaenol ar gyfer dylunio ac optimeiddio cenadaethau ac offerynnau. Rydw i ac rydw i wedi bod yn rhan o ddatblygu gwahanol efelychwyr , ac mae rhai ohonynt bellach ar gael i'r cyhoedd:
- 2024 – Taurex-Emcee (delfrydydd, aelod o'r tîm sy'n datblygu). Ategyn ar gyfer TauREx 3.1 sy'n darparu'r
Emcee sampler gan Dan Foreman-Mackey a chyfranwyr ar gyfer y dial. Ar gael yn gyhoeddus ar PyPI,
GitHub. - 2023 – PAOS (aelod o'r tîm sy'n datblygu). PAOS, yr Efelychydd Opteg Corfforol, yn gyflym, modern, a
pecyn Python dibynadwy ar gyfer astudiaethau Opteg Corfforol. Cyrch Gofod Ariel (ESA). Ar goedd
Ar gael ar PyPI, a GitHub. - 2022 – ExoSim 2.0 (unig ddatblygwr). Yr efelychydd parth amser newydd ar gyfer arsyllfeydd exoplanet. Defnyddir gan Genhadaeth Ofod Ariel (ESA) a'r genhadaeth EXCITE (NASA). Ar gael yn gyhoeddus ar PyPI a GitHub.
- 2021 – ExoRad (unig ddatblygwr). Mae'r efelychydd radiometrig generig: mae'n fersiwn gyffredinol ac wedi'i optimeiddio o ArielRad, sydd bellach yn cael ei ddefnyddio gan Genhadaeth Ofod Ariel (ESA), cenhadaeth EXCITE (NASA), Twinkle (BSSL), a Mauve (BSSL). Ar gael yn gyhoeddus ar PyPI, GitHub, ASCL.net, a Zenodo. Mwy na 29k downloads.
- 2021 - Rapoc (unig ddatblygwr). Mae Rapoc yn defnyddio mesuriadau amsugno moleciwlaidd (h.y. anhrylomenedd sy'n dibynnu ar donfedd) i gyfrifo anhryloeddau cymedrig Rosseland a Planck a ddefnyddir yn gyffredin mewn modelu atmosfferig. Ar gael yn gyhoeddus ar PyPI ac ar GitHub. Gweler hefyd EMAC a ASCL.net. Mwy na 6k downloads.
- 2021 – Alfnoor (prif ddatblygwr). Mae'r efelychwr arsylwi Ariel golau mil: lapio o ArielRad / ExoRad a TauREx3 i gynhyrchu sbectra arsylwyd efelychiadol o boblogaethau planedol cyfan. Cod ffynhonnell ar fynediad cyfyngedig.
- 2019 – ArielRad (prif ddatblygwr). Efelychydd radiometrig Ariel: cod sy'n amcangyfrif y perfformiad llwyth tâl wrth arsylwi targed, gan chwalu'r sŵn i'w gydrannau. Fersiwn ar-lein ar gael ar ExoDB ar gyfer aelodau Consortiwm Ariel. Cod ffynhonnell ar fynediad cyfyngedig.
