In Bayer and Macrì (J Am Math Soc 27(3):707–752, 2014), the first author and Macrì constructed a family of nef divisors on any moduli space of Bridgeland-stable objects on a smooth projective varietyX. In this article, we extend this construction to the setting of any separated schemeYof finite type over a field, where we consider moduli spaces of Bridgeland-stable objects onYwith compact support. We also show that the nef divisor is compatible with the polarising ample line bundle coming from the GIT construction of the moduli space in the special case whenYadmits a tilting bundle and the stability condition arises from a-stability condition for the endomorphism algebra. Our main tool generalises the work of Abramovich–Polishchuk (J Reine Angew Math 590:89–130, 2006) and Polishchuk (Mosc Math J 7(1):109–134, 2007): given a t-structure on the derived categoryonYof objects with compact support and a base schemeS, we construct a constant family of t-structures on a category of objects onwith compact support relative toS.
