DESCRIPTION:The existence of dark matter\, which constitutes 85% of the ma
 tter density and 26% of the total energy density\, is clearly demonstrated
  by cosmological observations of the Universe. And yet\, very little is kn
 own about the nature of dark matter. The observations support the ‘cold 
 dark matter’ (CDM) paradigm\, in which the dark matter is a heavy partic
 le\, with little to no interactions through fundamental forces other than 
 gravity. The cosmological and astrophysical observations of dark matter’
 s gravitational interaction currently provide the only robust evidence of 
 dark matter. These observations typically rely on characterising the distr
 ibution of matter in the Universe. A dark matter particle that is lighter 
 than the standard CDM paradigm predicts imprints a suppression of structur
 e in the matter distribution. The exact scale where this happens is most o
 ften linked to the mass of the dark matter particle. I will present new re
 sults on the thermal relic warm dark matter constraints using the high-red
 shift cosmic web as traced by the Lyman-alpha forest.
