ZTF Survey

A petite woman with grand ideas about the future of the Palomar Observatory! Read this article about Mansi Kasliwal , our @ztfsurvey PI and a professor of astronomy at @Caltech who was selected as the next director of the iconic observatory near San Diego alumni.caltech.edu/techer/stories…

Excellent PhD and postdoc opportunities with DZA (German Center for Astrophysics) in Germany in the field of multi-messenger astronomy and astrophysics. DZA is a major partner in @ztfsurvey. Learn more jobs.deutscheszentrumastrophysik.de/en-GB/jobs/734…

From @VRubinObs to Babamul and then to astronomers around the world. We flipped the switch to our @Caltech -led Babamul broker as an explosion of alerts about cosmic explosions & varying or moving objects in the sky has started flowing from @VRubinObs. ztf.caltech.edu/new/babamul-go…

Our partners @Stockholm_Uni stumbled upon a very weird "typical" supernova in @ztfsurvey data. This cosmic weirdo not only didn't faint steadily, but also lacked its usual hydrogen/helium surroundings. Check our latest science vlog for more youtube.com/watch?v=DiUeu7…

A massive star in the Andromeda galaxy quietly disappeared! Our former @ztfsurvey @Caltech PhD, Kishalay De, now at @Columbia discovered its sneaky move in archival data from NEOWISE. Did it turn into a black hole without exploding? news.columbia.edu/news/scientist…

Ready for discoveries! Our @ztfsurvey public data release is now available via @caltechipac IRSA platform, and it adds a full year of ZTF observations up to Oct 2025. We are now close to 70M single-exposure images and 5.3 B lightcurves! ztf.caltech.edu/ztf-public-rel…

"I would like to thank my long-term collaborators and the engineering crew and members of the Palomar Transient Factory and the Zwicky Transient Facility for their immense contribution to the projects," - says Shri

Congratulations to our @ztfsurvey architect and visionary Shri Kulkarni, who was awarded a gold medal from the @RoyalAstroSoc for 2026. This is RAS's highest honor, dating back 200 years , with former awardees including A. Einstein, Hubble, and S Hawking! ras.ac.uk/news-and-press…

First discovered by @ztfsurvey and featured at the #AAS247 press event, AT2024wpp is a rare & fast cosmic explosion that shed light on how these transients originate. The study is led by our collaborator Dan Perley. Watch from 23.55s youtube.com/watch?v=UiBq0K…

Anna is at the forefront of investigating FLBOTs - rare, fast-evolving, extremely bright cosmic explosions whose origin and underlying physics are just beginning to be understood. She and her collaborator Dan Perley (LJMU) announce one such rare event at the #AAS247.

Congratulation to Anna Ho, an assistant prof @Cornell who received the Pierce Prize in Astronomy at the #AAS247. Anna advanced her academic career as a student, postdoctoral researcher, and now professor, studying rare explosions with @ztfsurvey.

Triggered by LIGO/Virgo, ZTF scanned the night sky looking for an optical transient. It found one and the unfolding story is more gripping than a Hollywood movie....

The next issue of the @ztfsurvey newsletter is out! In addition to the usual science news and stories from our students, do not miss the open call for proposals. Anyone interested in observing with ZTF can apply! sites.astro.caltech.edu/ztf-newsletter…

Mansi and Prof. Varun Bhalerao (IIT Bombay), who is a long-term collaborator with Prof. Ajay Sood, Principal Scientific Advisor to India's prime minister

During her brief visit to India, Mansi Kasliwal met the Minister of Science and Technology and other prominent figures who shape the scientific vision & opportunities in the country. She also spoke to the finance minister about the importance of public outreach.

For all our @ztfsurvey partners and friends in or around New Delhi, India: Our PI, Mansi Kasliwal, will give a public lecture at the Nehru Planetarium tomorrow, Nov 6. Mansi will share stories about discovering spectacular and mind-boggling cosmic fireworks in the universe.

We never have to wait too long before @ztfsurvey reveals yet another spectacular event in the cosmos. This time, it was the brightest and most distant black hole flare outshining 10 trillion suns!

A great article about @ztfsurvey PI Mansi Kasliwal that describes Mansi's professional journey and captures both her child-like sense of exploration and her unique mix of grit & creativity.

Congratulations to our @ztfsurvey PI Mansi Kasliwal, who was just appointed the next director of @Caltech Palomar Observatory . From a PhD student, to an internationally recognized astronomer, Mansi's journey has been deeply connected to Palomar!

A recent open-access article published in @PASPJournal addresses the question: "IIb or not IIb" through a study of @ztfsurvey (ZTF) kilonova imposters. iopscience.iop.org/article/10.108…. -JGM
