Ultra-light dark m atter (ULDM) is a compelling and phenomenologically rich candidate for the cosmological dark matter. ULDM is typically considered to be a (pseudo)sc alar or a vector field\, but even more interesting and unique physics can be realised for spin-2 tensor fields.

In this talk I will review how spin-2 dark matter arises from the only known consistent modification of gravity to include multiple spin-2 fields\, and discuss (a) how the UL DM spin changes the properties of idealised haloes obtained through isolat ed soliton mergers\, (b) how to detect spin-2 ULDM using pulsar-timing dat a\, in particular how to detect perturbations in binary systems with machi ne-learning techniques\, and (c) how to detect spin-2 ULDM with gravitatio nal wave interferometers\, with an emphasis on existing LIGO/Virgo data. < /p> END:VEVENT END:VCALENDAR
