My first paper is up on arXiv as of a week ago!!! We used the ~1500 Type Ia supernovae from the Dark Energy Survey to measure time dilation from the expansion of the Universe 🔭 arxiv.org/abs/2406.05050 1/4

The Dark Energy Survey Supernova Program: Slow supernovae show...

We present a precise measurement of cosmological time dilation using the light curves of 1504 type Ia supernovae from the Dark Energy Survey spanning a redshift range $0.1\lesssim z\lesssim 1.2$....

Using most model independent method to find time dilation so far and the sheer number of high redshift SNe allow the most precise constraint on expansion induced time dilation: a factor of (1+z)^b, where we find b=1.003+/-0.015. This is what we expected, so cosmology can rest easy! 🔭 2/4
