The CMB sheds light on galaxy clusters: Observing the kSZ signal with ACT and BOSS

Like X-rays shining through your body can inform you about your health, the cosmic microwave background (CMB) shining through galaxy clusters can tell us about the universe we live in. When light from the CMB is distorted by the high energy electrons present in galaxy clusters, it’s called the Sunyaev-Zel’dovich effect. A new 4.1σ measurement … Continue reading The CMB sheds light on galaxy clusters: Observing the kSZ signal with ACT and BOSS

The dawn of multi-messenger astronomy: using KamLAND to study gravitational wave events GW150914 and GW151226

After the chirp heard ‘round the world, the search is on for coincident astrophysical particle events to provide insight into the source and nature of the era-defining gravitational wave events detected by the LIGO Scientific Collaboration in late 2015. By combining information from gravitational wave (GW) events with the detection of astrophysical neutrinos and electromagnetic … Continue reading The dawn of multi-messenger astronomy: using KamLAND to study gravitational wave events GW150914 and GW151226
