Abstract

Over the past two decades, tight correlations between black hole masses () and their host galaxy properties have been firmly established for massive galaxies () at low- (), indicating coevolution of supermassive black holes and galaxies. However, the situation at high-, especially beyond cosmic noon (), is controversial. With a combination of \emph{JWST} NIRCam/wide field slitless spectroscopy (WFSS) from FRESCO, CONGRESS and deep multi-band NIRCam/image data from JADES in the GOODS fields, we study the black hole to galaxy mass relation at z1--4. After identifying 18 broad-line active galactic nuclei (BL AGNs) at (with 8 at ) from the WFSS data, we measure their black hole masses based on broad near-infrared lines (Pa , Pa , and He\,I 10833\,Å), and constrain their stellar masses () from AGN-galaxy image decomposition or SED decomposition. Taking account of the observational biases, the intrinsic scatter of the relation, and the errors in mass measurements, we find no significant difference in the ratio for 2.5 z 4 compared to that at lower redshifts (), suggesting no evolution of the relation at up to z4.
