about me

Fan XiLong , Newton  Fellow (2012)

My current work focus on mutil-messenger (GW-EM) astrophysics [13].  With the help of EM data (such as galaxy catalog) and GW-EM theoretical prediction (such GW-GRB relation), I try to improve the gravitational waves signals detection with the LIGO-Virgo  instruments. In particular, I work on a Bayesian  approach to multi-messenger astronomy, with special interest on GW-EM source  sky localization, GW parameter estimation  [8,9]  and EM counterpart properties  [15].

I have spent 3 years understanding the EM data during  my Ph.D  phase, in particular galaxy properties by galactic chemical and SED models [ 4,5,6].

Before that,  I spent 3 years  understanding GW research during  my Master degreed phase ,  in particular GW burst sky localization [2],  stochastic  GW background detection [1,3] and continuous GW detection ([ 10]).

To help students building their own research, I contribute myself to  the research  of  GRB offset [7].

Very recently,  I am  also  interested in the strong lensed  GW-EM system and  their applications  on  fundamental questions (e.g. the speed of GW [12]  and the  Hubble constant [14,16] )
