Description: New ALMA observations of Abell 1795's central galaxy using ${}^{13}$CO(2-1) revealed molecular filaments extending 5--7 kpc, closely associated with radio bubbles from the central AGN. This tracer provided a more reliable measurement of molecular gas mass, yielding masses of (0.1--2) x $10^9$ M$ ext{}_ ext{odot}$, implying a lower CO-to-$ ext{H}_2$ conversion factor than standard assumptions.
