Trosolwyg
Rwy'n ymchwilydd mewn astroffiseg tonnau disgyrchol. Rwy'n canolbwyntio ar ddadansoddi signalau tonnau disgyrchol go iawn yn ogystal â data efelychiadol i gasglu priodweddau ffynonellau tonnau disgyrchol.
Mae gen i ddiddordeb arbennig mewn uno twll du deuaidd gydag orbitau ecsentrig neu troelli camlinio iawn gan y gall y llofnodion hyn nodi bod y binaries wedi'u ffurfio mewn amgylcheddau deinamig.
Mae gen i ddiddordeb hefyd mewn deall y systematics tonffurf a'r cyfyngiadau dulliau dadansoddi data cyfredol ar gyfer y genhedlaeth nesaf o synwyryddion tonnau disgyrchol.
