Classification of High-resolution Solar Hα Spectra using t-distributed Stochastic Neighbor Embedding

Meetu Verma, Gal Matijevič, Carsten Denker +7

The Hα spectral line is a well-studied absorption line revealing properties of the highly structured and dynamic solar chromosphere. Typical features with distinct spectral signatu…

Solar observatory Einstein Tower -- Data release of the digitized solar full-disk photographic plate archive

Partha S. Pal, M. Verma, J. Rendtel +3

We present solar full-disk observations, which were recorded at the Einstein Tower during the years 1943 - 1991 (Solar Cycles 18 - 22). High-school students from Potsdam and Berlin…

Periodicity search for Pulsar Binaries with TESS

Partha Sarathi Pal, P. H. T. Tam, Weitang Liang +4

Pulsar binaries, in particular redback systems, provide good sources to study the pulsar wind flow and its interaction with the companion stars. {\it Fermi}-LAT have proposed proba…

Endoreversible Otto engines at maximal power

Zackary Smith, P. S. Pal, Sebastian Deffner

Despite its idealizations, thermodynamics has proven its power as a predictive theory for practical applications. In particular, the Curzon-Ahlborn efficiency provides a benchmark…

Stochastic thermodynamics of relativistic Brownian motion

P. S. Pal, Sebastian Deffner

Physical scenarios that require a relativistic treatment are ubiquitous in nature, ranging from cosmological objects to charge carriers in Dirac materials. Interestingly all of the…
