For “her contributions to the development of high energy neutrino astronomy in the PeV energy region”.

Dr. Lu Lu is currently working at the Wisconsin IceCube Particle Astrophysics Center at the University of Wisconsin–Madison as an assistant professor in physics. She completed her PhD at the University of Leeds, UK, under the supervision of Professor Alan Watson. Her research focused on developing a novel technique to search for ultra-high-energy photons using data from the Pierre Auger Observatory. During that time, she was also at the University of Wuppertal, Germany, with supervision from Professor Karl-Heinz Kampert. Later, she joined Professor Shigeru Yoshida’s group at Chiba University, Japan, as part of the IceCube Collaboration. There, she played a leading role in the initial design of the D-Egg, a two-PMT optical module for the IceCube upgrade. She also made key contributions to the multimessenger correlation studies of the neutrino source candidate TXS0506+056 and the detection of a particle shower associated with the hadronic decay of a resonant W boson.

Her current research focuses on diffuse high-energy astrophysical/cosmogenic neutrinos from TeV to EeV, Galactic PeVatron detection in the context of multimessenger observations, and the exploration of potential transient ultra-high-energy sources. She is actively involved in IceCube outreach initiatives and has pioneered the development of an app that provides IceCube real-time alerts via augmented reality on mobile devices. Currently, she serves as co-lead of the diffuse science working group in IceCube and is one of the three representatives of the physical science group of US-SCAR (Scientific Committee of Antarctic Research).

For “his leading theoretical contributions to connecting beyond-Standard-model particle physics with astrophysics and cosmology”.

Dr. Andrea Caputo obtained his Master’s Degree in Theoretical Physics from the University of Rome La Sapienza. He then won an ITN Marie Curie Doctoral Fellowship and moved to the University of Valencia, Spain, where he got his PhD in 2020. His thesis, which focused on innovative ways to investigate beyond the standard model physics, mainly dark matter and neutrinos, got the Best Thesis Prize of the University. He then moved to Israel where he held a joint postdoc position between Tel Aviv University and Weizmann Institute. After 2 years in Israel, he joined CERN Theory Division in Geneva, where he is currently a Senior Fellow.

Andrea’s research focuses on the use of a variety of astrophysical probes to shed light on dark matter properties. Among the other things, he pioneered the use of line intensity mapping to detect axion dark matter, the use of Low-Energy Supernova to discover new physics at the ~MeV scale, as well as the use of Lyman-alpha lines to single out dark matter energy injections in the interstellar medium. For his research, Andrea won various grants and prizes, including an Individual Marie Curie Fellowship and the “Giuliano Preparata Prize” from the Italian Society of Physics.

Hubble Fellow, University of Wisconsin-Madison, USA

Dr. Siyao Xu, received the 2019 IUPAP Young Scientist Award during the 36^th International Cosmic Ray Conference held in Madison, USA for fundamental theoretical contributions to Astroparticle physics that reveal profound connections among diverse phenomena.”

Siyao Xu is currently a Hubble Fellow at the University of Wisconsin-Madison. She completed her Ph.D at Peking University (Beijing, China) under the supervision of Professor Bing Zhang in 2017. Her thesis on magnetohydrodynamics (MHD) turbulence and its astrophysical applications was recognized with the 2017 International Astronomical Union (IAU) Ph.D Prize and the 2019 Cecilia Payne-Gaposchkin Doctoral Dissertation Award in Astrophysics. Her research focuses on understanding of the fundamental physics of cosmic ray propagation and particle acceleration in high-energy astrophysical environments. Her work demonstrates that the key to studying cosmic ray propagation is to obtain a proper description of MHD turbulence. Her pioneering theoretical studies have been applied for addressing diverse and long-standing astrophysical problems related to gamma-ray bursts, pulsar wind nebulae, and supernova remnants to name a few.

DESY Zeuthen and F.A. University Erlangen, Germany

Prof. Anna Nelles, received the 2019 IUPAP Young Scientist Prize during the 36^th International Cosmic Ray Conference in Madison, USA for her outstanding contributions to the development of the new technique of the radio detection of cosmic rays and neutrinos.

Prof. Anna Nelles competed her Ph.D in 2014 at Radboud University Nijmegen, the Netherlands under supervision of Prof. J.R. Hörandel. She had a key role in connecting the activities of the LOFAR radio telescope in Europe with the Auger Engineering Radio Array located in Argentina that contributed to development of radio detection of air showers. Her subsequent postdoctoral work at University of California, Irvine on the ARIANNA project led to significant breakthroughs in detection of ultra-high energy neutrinos. She now holds a joint appointment at DESY Zeuthen and Friedrich Alexander University in Erlangen Nuremberg both in Germany. Her current focus continues to be on the radio detection of neutrinos in challenging but pristine environments of Antarctica and Greenland.

Dr. Frank Schröder received the IUPAP Young Scientist Prize in Astroparticle Physics 2017 for his outstanding contributions to cosmic ray physics in general and to the development of radio observations of extensive air showers in particular. After finishing his undergraduate studies of physics with a Diploma from Technische Hochschule Darmstadt (Germany) in July 2007 about detector development for Axion searches, Frank started his PhD in Physics at KIT to study in detail the radio detection technique of high energy cosmic rays at the air shower experiments LOPES in Karlsruhe and the Pierre Auger Observatory in Argentina. After completing his three years PhD study in February 2011 with best marks, he initialised and started his first own project at the Tunka facility in Siberia, where he optimised the radio detection technique. The project was driven by the idea to answer experimentally the question about the sensitivity of the radio signal to the primary mass of the cosmic rays. The success of Tunka-Rex lies in the first experimental correlation of longitudinal shower observations of the radio and Cherenkov light components of extensive air showers. Moreover, he could proof that radio observations allow to reconstruct the shower maximum and the energy of extensive air showers with a quality similar to those of conventional detection techniques. As visiting scientist at the Universidad Nacional de San Martin, Buenos Aires, Argentina in 2013 and at his renewed postdoc position at KIT he further improved his impressive publication record in high-ranking Journals and wrote a comprehensive review article on the radio detection technique.

Dr. hab. Julian Sitarek received the IUPAP Young Scientist Prize in Astroparticle Physics 2017 for his distinguished contributions to high energy astrophysics in general and to TeV gamma-astronomy in particular. He has graduated in Physics at the University of Lodz at the age of 23 and continued for a PhD project at University of Lodz (Poland) and Max Planck Institut für Physik in Munich (Germany). He received his PhD in Astrophysics at the age of 26 based on his contribution to the analysis of data from the MAGIC telescopes and for the development of models for gamma-ray production in cascade processes in active galaxies. Next, he moved for a 3 year postdoc position to the Instituto de Fisica d’Altes Energies (IFAE, Barcelona, Spain) and returned to University of Lodz in 2014 to take a permanent position at the Department of Astrophysics. He continued his very active contribution to the MAGIC Collaboration serving as the coordinator of the software group and one of the coordinators of the AGN group and also continued his interest in theoretical investigation of models for the high energy processes in galactic and extragalactic sources. At the age of 32 he completed a habilitation based on his contribution to the development of the analysis techniques and performance of the MAGIC stereo system and the discovery of gamma-ray emission from a few extragalactic sources, becoming one of the youngest researchers with the degree of habilitation in Poland. Recently, he obtained a prestigious 3 year fellowship for the young researchers from the Polish Ministry of Science and Higher Education and became a principal investigator of the grant from the National Research Center.
