微小却具有强大影响力？矮星系与黑洞在 dwarf 区域的共同演化

该项目利用维拉·C·鲁宾天文台及其他巡天数据，研究超大质量黑洞在矮星系中的影响。通过分析这些活跃吸积黑洞的时变辐射特征，研究旨在将黑洞的活动性与宿主星系的性质进行关联分析。

About the project While supermassive black holes are widely known to reside in almost all massive galaxies, studies of supermassive black holes in low-mass "dwarf" galaxies are in their infancy. In this project you will use new survey data from the Vera C. Rubin Observatory and other facilities to understand how black holes impact their host galaxies in the dwarf regime. Selecting actively accreting black holes through their characteristic time-varying emission, unlocks the potential to unearth new populations of low-mass black holes that cannot be identified using other selection techniques. Variability selection is on the cusp of being transformed with the arrival of data from the Vera C. Rubin Observatory Legacy Survey of Space Time (LSST), which has now begun full survey operations and will image the entire southern sky every few days, building up a time-lapse cosmic movie of our Universe. LSST will allow low-mass black holes to be routinely detected out to redshift 1. In this project you will utilise data from LSST and combine with other survey data e.g. from VISTA, Euclid, Roman and 4MOST, to connect the time-varying signatures of black hole accretion with the properties of the host galaxy in which these black holes reside. Potential directions include: measuring the stellar masses and star formation rates of the host galaxies of variability selected AGN using LSST and VISTA understanding the morphologies of variability selected AGN in the dwarf and massive galaxy regime using Euclid/Roman constraining the black hole masses and accretion rates of variability selected AGN using 4MOST spectra You will have the opportunity to work on the new survey data and join teams within large international collaborations exploiting new statistical techniques to identify and understand black hole activity. You will also be able to shape the direction of the project based on your own interests.
