Intracluster Light with Euclid: Forecasting Euclid’s capabilities for ICL detection
The Euclid space telescope presents an exciting opportunity to delve into the processes which form and evolve galaxy clusters. An important aspect of the evolution of clusters is the formation of diffuse intracluster light (ICL) within cluster haloes, which offers an insight into a cluster’s dynamics and assembly history. Since ICL is very diffuse, detecting and quantifying it presents a challenge. I will demonstrate Euclid’s transformative potential to constrain the evolution of the ICL fraction over cosmic time with unprecedented sample sizes and precision. We have been forecasting the limits with which Euclid will be able to detect ICL by analysing simulated clusters across a range of halo masses, redshifts and ICL parameters (fraction of ICL, effective radius, sersic index). We will explore ‘idealised’ signal-to-noise ratios for ICL detections across this parameter space in NIR H-band, and compare with results from different ICL fitting routines, in order to forecast the effectiveness with which Euclid will be able to detect ICL in future observations. We also estimate the expected sample sizes of clusters in which we will detect ICL across the Euclid Wide Survey.
