Abstract
Over the past two decades, tight correlations between black hole masses ($M_{\bullet}$
) and their host galaxy properties have been firmly established at $\mathrm{low}-z$
($z < 1$
), indicating coevolution of supermassive black holes and galaxies. However, the situation at $\mathrm{high}-z$
, especially beyond cosmic noon ($z \gtrsim 2.5$
), is controversial. With a combination of 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 $z \sim 1-4$
. After identifying $18$
broad-line active galactic nuclei (BL AGNs) at $0.9 < z < 3.6$
(with $8$
at $z > 2.5$
) from the WFSS data, we measure their black hole masses based on broad near-infrared lines ($\mathrm{Pa}\alpha$
, $\mathrm{Pa}\beta$
, and $\mathrm{HeI}\lambda10833\,\mathrm{\AA}$
), and constrain their stellar masses ($M_{\ast}$
) from AGN-galaxy image decomposition or SED decomposition. Taking account of the observational biases, the intrinsic scatter of the $M_{\bullet}-M_{\ast}$
relation, and the errors in mass measurements, we find no significant difference in the $M_{\bullet}/M_{\ast}$
ratio for $2.5 < z < 3.6$
compared to that at lower redshifts ($1 < z < 2.5$
), suggesting no evolution of the $M_{\bullet}-M_{\ast}$
relation up to $z \sim 4$
.
