Spectroscopic studies of Themis family asteroids with SEDM

 
Changed:
<
<		Abstract: We examine all ZTF observations of known comets to measure their brightness and morphologies. We are looking for deviations from their baseline activity trends in order to discover outbursts, and identify events for follow-up studies.
>
>		Study reflectance spectra of Themis family asteroids at different orbital phases, to investigate the potential presence of water ice and its variability with heliocentric distance.
 
Changed:
<
<		We use the ZChecker ( UMD, Caltech) software for outburst discovery (user: ztf, password: enckeekcne).

NEO and small body discoveries with ZTF

 
Changed:
<
<		Lead: Quanzhi Ye, Chengxing Zhai
>
>		Identify, discovery, and measure astrometry of near-Earth objects, objects interior to Earth/Venus orbit, interstellar objects. Exploit ZTF surveys with ZStreaks, DeepStreaks, ZMODE, and Tails.
 
Changed:
<
<		Abstract: testing the synthetic tracking technique.

Sparse/Long-term lightcurve fitting

>		NEOZTF Scanning Instructions
 
Changed:
<
<		Lead: Lynne Jones (there is overlap with projects by Rex Chang, and Daniela Huppenkothen is the lead for the Gaussian Processes portion of the project, which includes non-ZTF experiments and data too).
>
>		Team: George Helou, Tom Prince, Kumar Venkataramani, Quanzhi Ye, with contributions from students and follow-up observers
 
Changed:
<
<		Abstract: We are attempting to understand best methods for fitting rotation curves, and (next-up) phase curves, for known asteroids detected by ZTF. Currently we are using the alert photometry, but hope to extend this to using matchfile photometry. One area of investigation is fitting the rotational light curve with simple two-component Fourier models; another area is fitting lightcurves with Gaussian Processes.

NEO co-discovery with Sierra Remote Observatory

Changed:
<
<		I have conducted a rotation period survey using CNEOST (China) and KMTNet (Korea) for my master thesis. I would like to continue this work using sparse lightcurve obtained by ZTF. The fitting method includes Fourier series and HG.

Prompt cometary outburst discovery and follow-up

<
<		Supervisor: Mario Juric
>
>		We examine all ZTF observations of known comets to measure their brightness and morphologies. We are looking for deviations from their baseline activity trends in order to discover outbursts, and identify events for follow-up studies.
 
Changed:
<
<		We have built a minor planet detection linking algorithm capable of discovering moving objects at high completeness without the need to build or observe tracklets. We have run it on two weeks of ZTF detections (finding 97% of all known moving objects with at least 5 detections) and are now working on running it on all of ZTF's detections.
>
>		We use the ZChecker software to process ZTF data nightly. Online interface at zbrowser2.mkelley.dev, contact Mike Kelley for access.

Archival cometary outburst search and summary

 
Changed:
<
<		The rotation periods of TNOs are very limited. We have extracted the light curves of TNOs from ZTF archive PSF source catalogs and are analyzing thier rotation periods and phase curve. We hope to add some reliable rotation periods of TNOs to the current inventory.
>
>		Identify all cometary outbursts in ZTF data. Analyze results as a statistical data set, and investigate individual events on a case-by-case basis.
