Dr. Lulu Fan （范璐璐）
My research interests:
- • Galaxy formation and co-evolution with their central supermassive black holes;
- • Galaxy morphology and structure;
- • Data reduction pipeline for Wide Field Survey Telescope (WFST);
Topic I: Multi-wavelength studies of hyper-luminous, dust-obscured quasars at cosmic noon
- ✓ Hot dust-obscured galaxies (thereafter, Hot DOGs) have been recently discovered in Wide-field Infrared Survey Explorer (WISE) All-Sky Survey. Following the predictions by the mainstream model of galaxy formation and evolution, Hot DOGs have been suggested to locate in the transition phase between sub-millimeter galaxies and quasars at high redshift. They are good candidates for studying the co-evolution between massive galaxies and their central supermassive black holes. Combined our ALMA, VLT, JCMT, P200, EVN/VLBA observations with HST, SDSS, WISE and Herschel archival data, we study the physical properties (morphology, stars, atomic and molecular gas, dust…) and environments of Hot DOGs. A series of our works have been or will be published (Fan et al., 2016a, 2016b, 2017, 2018a, 2018b, 2019).
Topic II: Galaxy morphology and structure
With the high-resolution images of HST, my interests are to study:
- • morphological classification, especially by employing the machine learning (ML) technology in the Big Data era;
- • the origin of Hubble sequence;
- • the evolution of galactic structure and its dependence on other properties;
- • the morphology and structure of AGN;
The Hubble Sequence throughout the Universe's history
From Wikipedia
In the near future, the new space telescope, such as China Space Station Telescope (CSST), EUCLID (Europe, ESA) and Roman Space Telescope (USA, NASA), will raise both the huge chances and challenges to the studies of galaxy morphology and structure.
Topic III: Data reduction and storage system of Wide Field Survey Telescope (WFST)
- ✓ University of Science and Technology of China (USTC) and Purple Mountain Observatory (PMO) are jointly building a 2.5m-aperture Wide Field Survey Telescope (WFST) and plan to carry out a multiband time-domain imaging survey. The site is located in Lenghu, Qinghai.
- ✓ I am organizing a team, mostly consisting of young researchers, post-doc and graduate students from Department of Astronomy at USTC, NAOC and PMO, to develop the WFST data reduction and storage system.
