This paper focuses on how insolation affects the nucleus of comet 67P/Churyumov-Gerasimenko over its current orbit. We aim to better understand the thermal environment of the nucleus, in particular its surface temperature variations, erosion, relationship with topography, and how insolation affects the interior temperature for the location of volatile species (H2O and CO2). Methods. We have developed two thermal models to calculate the surface and subsurface temperatures of 67P over its 6.45-year orbit. The first model, with high resolution (300 000 facets), calculates surface temperatures, taking shadows and self-heating into account but ignoring thermal conductivity. The second model, with lower resolution (10 000 facets), includes thermal conductivity to estimate temperatures down to ∼3 m below the surface. Results. The thermal environment of 67P is strongly influenced by its large obliquity (52◦), which causes significant seasonal effects and polar nights. The northern hemisphere is the coldest region, with temperatures of 210-300 K. H2O is found in the first few centimetres, while CO2 is found deeper (∼2 m) except during polar night around perihelion, when CO2 accumulates near the surface. Cliffs erode 3-5 times faster than plains, forming terraces. The equatorial region receives maximum solar energy (8.5×109 J m-2 per orbit), with maximum surface temperatures of 300-350 K. On the plains, H2O is found in the first few centimetres, while CO2 is found deeper (∼2 m) and never accumulates near the surface. In the southern hemisphere, a brief intense perihelion heating raises temperatures to 350-400 K, which is followed by a 5-year polar night when surface temperatures drop to 55 K. Here H2O remains in the first few centimetres, while CO2 accumulates shallowly during polar night, enriching the region. Erosion is maximal in the southern hemisphere and concentrated on the plains, which explains the observed overall flatness of this hemisphere compared to the northern one. Over one orbit, the total energy from self-heating is 17\% of the total energy budget, and 34\% for thermal conduction. Our study contributes to a better understanding of the surface changes observed on 67P.}, language = {en} } @inproceedings{LoesserSchlechtSchintkeetal.2025, author = {L{\"o}ßer, Ansgar and Schlecht, Max and Schintke, Florian and Witzke, Joel and Weidlich, Matthias and Scheuermann, Bj{\"o}rn}, title = {Fast Min-ϵ Segmented Regression using Constant-Time Segment Merging}, volume = {267}, booktitle = {Proceedings of the 42nd International Conference on Machine Learning}, pages = {40312 -- 40327}, year = {2025}, language = {en} } @article{AgarwalGreveReinefeldetal.2025, author = {Agarwal, A. and Greve, Nico and Reinefeld, Alexander and Schintke, Florian and et al.,}, title = {Performance of the prototype Silicon Tracking System of the CBM experiment tested with heavy-ion beams at SIS18}, volume = {1082}, journal = {Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment}, publisher = {Elsevier BV}, issn = {0168-9002}, arxiv = {http://arxiv.org/abs/2505.20517}, doi = {10.1016/j.nima.2025.171059}, pages = {171059}, year = {2025}, language = {en} } @article{JiAnitaFournier2025, author = {Ji, Hongchen and Anita, Ragyanszki and Fournier, Rene}, title = {Computational Study of the Reactions of CH2 with HCNO and HNCO}, volume = {103}, journal = {Canadian Journal of Chemistry}, number = {7}, doi = {10.1139/cjc-2024-0203}, pages = {386 -- 395}, year = {2025}, abstract = {We present a computational approach for screening reaction mechanisms with machine learning estimates of energy barriers. A comprehensive screening of thousands of reactions identified the CH2 reactions with HCNO and HNCO as possible sources of relatively complex organic molecules in space. We report detailed reaction mechanisms, including TS, intermediate, and product energies, calculated with density functional theory and coupled cluster theory. Singlet CH2, located 9 kcal/mol above the triplet ground state, reacts with HCNO or HNCO without a barrier, producing four prod11 ucts: CH2NCHO, N-methyleneformamide, the thermodynamically favored product; NHCHCHO, imine acetaldehyde; NHCHOCH; and (CH2OC)NH, oxiran-2-ylazanide. The lowest energy pathway for CH2 + HCNO, involving a triplet-to-singlet crossing, has a barrier of 8 kcal/mol and leads to N -methyleneformamide, imine acetaldehyde, and NHCHOCH. The reaction of triplet CH2 with HNCO has a lowest energy pathway with a barrier of 11 kcal/mol, yielding CH2(CO)NH.}, language = {en} } @misc{RamakiSchintke2025, author = {Ramaki, Niaz Mohammad and Schintke, Florian}, title = {Ensuring Reproducibility in Stream Processing with Blockchain Technologies}, journal = {2025 11th International Conference on Computer and Communications (ICCC)}, publisher = {IEEE}, doi = {10.1109/ICCC68654.2025.11437772}, pages = {1383 -- 1391}, year = {2025}, language = {en} }
