A Natural $≳ 100 \times$ Telescope: Discovery of the Strongly Lensed Type II SN 2025mkn at $z = 1.37$

Cameron Lemon, Ariel Goobar, Joel Johansson +90

We present the discovery of SN 2025mkn, a gravitationally lensed Type II supernova. First detected as a blue transient in ZTF, 0.83 $^{''}$ from a $z = 0.42$ elliptical gala…

Inferring the Hubble Constant Using Simulated Strongly Lensed Supernovae and Neural Network Ensembles

GonÃ§alo GonÃ§alves, Nikki Arendse, Doogesh Kodi Ramanah +1

Strongly lensed supernovae are a promising new probe to obtain independent measurements of the Hubble constant ( $H_{0}$ ). In this work, we employ simulated gravitationally lensed T…
