Preface: Advances in solar physics The idea for this special issue of Advances in Space Research (ASR) was formulated during the 14th European Solar Physics Meeting (ESPM-14) that took place in Dublin, Ireland in September 2014. Since ASR does not publish conference proceedings, it was decided to extend a general call to the international solar-physics community for manuscripts pertinent to the following thematic areas: 1. New and upcoming heliospheric observational and data assimilation facilities. 2. The Sun as a whole: large scale flows, magnetism, magneto-convection, and the solar cycle. 3. Emergence and evolution of magnetic flux in the solar atmosphere. 4. Chromospheric dynamics. 5. Heating and transient activity of the solar corona: waves, flows, reconnection, and jets. 6. Solar eruptive events: instabilities, flares, and coronal mass ejections. 7. Radio emission and particle acceleration. 8. The solar wind and space-weather research. As a result, a total of twenty-five (25) manuscripts were submitted for consideration. This issue consists of fourteen (14) original articles presenting latest results and developments, each refereed by at least two expert reviewers. These works showcase the wealth of theoretical and observational advances, data analysis and sophisticated modeling at work in contemporary solar physics. A number of articles are still under review and will appear in future ASR issues provided that they complete the review process successfully. This special issue features papers discussing data from state-of-the-art ground- and space-based facilities, sophisticated magnetohydrodynamic (MHD) modeling and theory. In brief, the indirect detection of a farside solar coronal mass ejection (CME) that nonetheless blocked galactic cosmic rays at such a degree that was detected by the ground-based muon hodoscope URAGAN (Astapov et al.) and the procedure of organizing of

real-time URAGAN data presented in the Internet (Yashin et al.); the effect of uncertainties in developing reliable inner-heliospheric solar-wind models by using the SOLIS full-Sun magnetic-field measurements (Pevtsov et al.); and the potential for groundbreaking studies of the solar chromosphere by the SSALMON network of the new ALMA facility (Wedemeyer et al.). Furthermore, three-dimensional MHD modeling of coronal condensations (a.k.a. coronal ‘‘rain”) aiming to match the latest SDO/AIA observations (Moschou et al.) and an analysis of the variations of solar acoustic oscillations in the course of the solar cycle (Broomhall et al.). The presented results also include the advanced modeling of Kelvin–Helmholtz instability in solar cool surges, addressing the peculiarities of their evolution (Zhelyazkov et al.); evidence of a blast shock-wave formation in the interaction of a CME with streamers (Zimovets et al.); a rare observation of a spatially-resolved type II radio burst with multiple lanes (Zimovets et al.) and identification of the drivers of the shocks associated with type II events (Cunha-Silva et al.), which shed lights on the physical processes accompanying a CME development; an important observation of multiperiodic pulsations during an X-class solar flare, which helps reveal the physical processes responsible for flaring quasi-periodic pulsations (Chowdhury et al.); the study of space-frequency distribution of oscillations at different atmospheric levels of the Sun with the use of EUV and radio data (Kolobov et al.); and advanced analytical theory of MHD discontinuities (Ledentsov et al.). This special issue would not have been possible without the help and sage advice of Dr. Peggy Ann Shea, ASR Co-Editor for Special Issues, and Journal Manager, Mrs. Rosie Stewart. We are indebted to them for their support. Thanks are also due to all the authors who submitted contributions and to our expert reviewers who put valuable time and effort helping to make these contributions suitable for publication. The names of all reviewers who agreed to be identified are listed at the end of this issue. Last but certainly not least, we thank in advance the diverse readers of this issue who can help make it a success. To these knowledge-seekers we wish an enjoyable and beneficial reading.
