FINE STRUCTURE OF ANOMALOUSLY INTENSE PULSES OF PSR J0814+7429 RADIO EMISSION IN THE DECAMETER RANGE
Purpose: The fine structure of the anomalously intense pulses of PSR J0814+7429 (В0809+74) has been studied. The pulsar radio emission fine structure is investigated to determine its parameters in the lowest part of spectrum available for groundbased ...

Extended Emission from the PSR B1259-63/SS 2883 Binary Detected with Chandra
PSR B1259-63 is a middle-aged radio pulsar (P=48 ms, tau=330 kyr, Edot=8.3*10^{35} erg/s) in an eccentric binary (P_orb =3.4 yr, e=0.87) with a high-mass Be companion, SS 2883.

A novel amino acid (aa)‐score‐based single‐position peptide clustering strategy is developed for peptidomics, enabling precise profiling of protein proteolysis in plasma from β‐thalassemia cohort. The method identifies new aa position‐based peptide cluster biomarkers validated by heavy‐labeled peptides, visualizes aggregated changes, uncovers disease ...

Calculation of radar signals delay to second order in the frame of the General Relativity Theory
From the Schwarzschild metric, the light delay due to a gravitational field is calculated to second order approximation in the gravitational potential. We analize the contribution of the second order terms for strong gravitational fields as the generated

HST optical polarimetry of the Vela pulsar & nebula
Polarisation measurements of pulsars offer an unique insight into the geometry of the emission regions in the neutron star magnetosphere. Therefore, they provide observational constraints on the different models proposed for the pulsar emission ...

Multi‐scale maternal behavioral responses by white‐tailed deer to coyote predation risk
In the piedmont region of the southeastern US, white‐tailed deer adjust maternal care strategies in response to variation in risk of encountering coyotes. In areas frequented by coyotes, adult female deer (i.e., does) increase their use of space, likely to avoid drawing coyotes to the location where a fawn is hidden.

Cherenkov Telescope Array Observatory: Die Zukunft der Gammaastronomie
Im Jahr 1989 hat das Wipple‐Observatorium die erste Quelle hochenergetischer Gammastrahlung entdeckt. 2002 waren dann sechs Quellen bekannt, 2024 schon mehr als 300. Und das ist immer noch lediglich die Spitze des Eisbergs in der jungen Geschichte der Gammaastronomie.

Red Noise Suppression in Pulsar Timing Array Data Using Adaptive Splines
Noise in Pulsar Timing Array (PTA) data is commonly modeled as a mixture of white and red noise components. While the former is related to the receivers, and easily characterized by three parameters (EFAC, EQUAD and ECORR), the latter arises from a mix ...
