ELAIS-N1 (northern field)
Dark energy, via Type Ia supernovae
What this is
A long-studied extragalactic field at high northern ecliptic latitude, giving Roman near-continuous visibility.
Two fields revisited every few days to catch supernovae rising and fading, with prism spectroscopy to classify them. Target: ~25,000 Type Ia below redshift 2.
No survey products yet. Products for ELAIS-N1 (northern field) will list here as MAST publishes them.
Pointing
