REMINDER -- IPMU Workshop on “Particle Acceleration in Solar Flares and the Plasma Universe”
by Mitsuo Oka 12 Oct '21

12 Oct '21

Dear All We would like to remind you that an online science meeting on "Particle Acceleration in Solar Flares and the Plasma Universe" will be held during November 15-19, 2021. This meeting is open to everyone who is interested in particle energization in space, solar, and astrophysical plasma environments. It is driven by the recent development of a next generation solar X-ray/gamma-ray mission named “PhoENiX” (to be proposed to JAXA for a launch slot in early 2030s). While this mission is designed to study particle acceleration and heating in solar flares, we wish to have interdisciplinary discussions because we believe the scientific results of the PhoENiX mission will make a significant impact not only on solar physics but also on space physics and astrophysics. Examples of invited talks include “multi-wavelength observations of solar flares”, “roles of magnetic reconnection in high-energy phenomena in different plasma environments”, and “theory and simulations of particle acceleration and fundamental plasma processes”. The meeting will be held during November 15-19, 2021 as a virtual, online-only event. The deadline for the abstract is 23:59 JST on October 19, 2021 while registration is open until November 15. For more information, please check the workshop website: https://indico.ipmu.jp/event/395/ Best regards Mitsuo (on behalf of SOC) Scientific Organizing Committee: Lindsay Glesener, Fan Guo, Tomoko Kawate, Dmitry Khangulyan, Säm Krucker, Noriyuki Narukage, Mitsuo Oka, Kathy Reeves, Taro Sakao, Tadayuki Takahashi, Yohko Tsuboi

RHESSI Nuggets in September 2021
by Hugh Hudson 06 Oct '21

06 Oct '21

http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets No. 416, “X-rays from a Type I Radio Burst,” by R. RAMESH. X-ray identification of the last remaining meter-wave burst type. No. 417, “Manifold Nonthermality,” by Marina BATTAGLIA et al. Even weak events involve multple instances of nonthermality. We welcome contributions to the RHESSI Nuggets, and the topics may wander some distance away from specifically RHESSI results if they are generally interesting. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets for these and others. Comments about specific flares can often be found by searching for their SOLyyyy-mm-dd identifier from this home page.

MAX MILLENNIUM NEWS 29 September 2021 CONTENTS 1. CALL FOR PAPERS "The Sun Seen with the ALMA - First Results" 2. E-PRINTS POSTED IN THE PAST WEEK 3. FROM THE EDITOR ===================================================================== 1. CALL FOR PAPERS ------------------ > From Costas Alissandrakis (calissan(a)uoi.gr) Article collection on first results of solar observations with ALMA We would like to draw the attention of colleagues and ask for contributions to an article collection on "The Sun Seen with the Atacama Large mm and sub-mm Array (ALMA) - First Results", to be published in Frontiers in Astronomy and Space Sciences/Frontiers in Stellar and Solar Physics as a Research Topic. With the roll-out of solar observing capabilities in 2016, the Atacama Large mm and sub-mm Array (ALMA) has been regularly observing the Sun with unprecedented spatial (~1") and temporal resolution (1s) in this wavelength range. The goal of this Research Topic is to make an assessment of what we have learned so far from ALMA observations of the Sun and thus put in perspective ALMA’s contribution to our understanding of the physical processes in the solar atmosphere while, at the same time, serve as a guide to future work. An additional goal is to identify observational/computational aspects that need to be addressed and thus help to improve the quality and value of the observations. To this end, it will include both review articles and original works. Submission deadlines: 29 October 2021 for abstracts, 28 February 2022 for manuscripts Editors: Costas Alissandrakis, Tim Bastian, Masumi Shimojo and Alexander Nindos For more information and submission details see https://www.frontiersin.org/research-topics/24755/ 2.

"FASR2021 workshop: Solar Physics with a Next, Generation Solar Radio Facility", Dec 1-3, 2021 (virtual). Website/registration are now open.
by Pascal Saint-Hilaire 28 Sep '21

28 Sep '21

Dear colleagues, Here is a workshop announcement that should be of interest to some of you. Best regards, --Pascal The need for a high-performance solar radio telescope in the United States has been recognized for many years. The FASR concept represents such a telescope, one that provides high-resolution imaging over a broad range of frequencies, sufficient to probe the solar atmosphere from the mid-chromosphere to the mid-corona, with high time and spectral resolution. EOVSA implemented many FASR design elements and, as such, has served as a valuable pathfinder instrument, spectacularly validating both the fundamental concept of time-resolved broadband imaging spectroscopy and the science it enables. In the meantime, science and technology have advanced and the need for full implementation of the FASR concept has only grown more important In anticipation of upcoming funding opportunities, this workshop is being convened from 2021 Dec 1-3 to highlight progress in solar physics over the past decade, and to take stock of the unique contributions enabled by the current suite of new radio instruments, to refine the science goals and requirements of a next-generation solar radio facility. The workshop will provide a forum to discuss relevant new and emerging technologies that will enable this new science. We invite colleagues with an interest in solar physics and radio technology, and from other fields that would stand to benefit, to help explore the frontiers of science and technology that will guide updates and refinements to the FASR concept. The workshop will be virtual, hosted from the University of California Berkeley's Space Sciences Laboratory (LOC: Pascal Saint-Hilaire, Milo Buitrago-Casas, Jim McTiernan, Gelu Nita). The Scientific and Technical Organizing Committee is composed of Marin Anderson (JPL), Tim Bastian (NRAO), Bin Chen (NJIT), James Drake (UMD), Dale Gary (NJIT), Lindsay Glesener (UMN), Gregg Hallinan (Caltech), Jonathon Kocz (UCB), Haosheng Lin (U. Hawaii), Sophie Musset (ESA), Dan Werthimer (UCB). Website and registration are at https://fasr21.ssl.berkeley.edu/. Deadline for contributions is November 1st, 2021. There is no deadline for participation. -- ======================================================================= Pascal Saint-Hilaire pascal(a)ssl.berkeley.edu Space Sciences Laboratory phone: +510-643-4618 University of California, Berkeley 7 Gauss Way Berkeley, CA-94720-7450 http://sprg.ssl.berkeley.edu/~shilaire/ =======================================================================
