Trosolwyg
Rwy'n astroffisegydd arsylwadol sy'n gweithio ar ffrwydradau cosmig, o'r enw supernovae, sy'n nodweddu marwolaeth seren. Mae fy ymchwil bresennol yn canolbwyntio ar y ffrwydradau uwchnofâu disgleiriaf, y cyfeirir atynt fel arfer fel "supernovae supernovae", a'u defnydd fel chwiliedydd newid uchel.
Mae gen i ddiddordeb hefyd yn rôl rhyngweithio a siociau ar transients seryddol, yn ogystal â'r rhai sy'n cyrraedd eu golau mwyaf ac yn pylu yn fuan ar ôl ychydig wythnosau, y cyfeirir atynt fel arfer fel transients Cyflym neu transients Cyflym, Glas, Optegol (FBOTs). Rwyf hefyd yn gweithio ar weithredu technegau dysgu peiriannau ar gyfer seryddiaeth dros dro i ddosbarthu a chategoreiddio gwahanol fathau o uwchnofâu a transients eithafol.
Yn ddiweddar, dyfarnwyd Gwobr MERAC 2021 i mi fel yr ymchwilydd Gyrfa Gynnar Gorau mewn Astroffiseg Arsylwadol am ymchwilio i eithafion ffrwydradau serol, gan ddarparu cyfraniad arloesol i'w dealltwriaeth a'u rôl mewn seryddiaeth ac astroffiseg.
