Wavelength-resolved Reverberation Mapping of quasar CTSC30.10: Dissecting MgII and FeII emission regions

We present the results of the reverberation monitoring aimed at MgII broad line and FeII pseudocontinuum for the luminous quasar CTS C30.10 (z = 0.90052) with the Southern African Large Telescope covering the years 2012-2021. We aimed at disentangling the MgII and UV FeII variability and the first measurement of UV FeII time delay for a distant quasar. We used several methods for time-delay measurements and determined both FeII and MgII time delays as well as performed a wavelength-resolved time delay study for a combination of MgII and FeII in the 2700 - 2900 \AA restframe wavelength range. We obtain the time delay for MgII of $275.5^{+12.4}_{-19.5}$ days in the rest frame, while for FeII we have two possible solutions of $270.0^{+13.8}_{-25.3}$ days and $180.3^{+26.6}_{-30.0}$ in the rest frame. Combining this result with the old measurement of FeII UV time delay for NGC 5548 we discuss for the first time the radius-luminosity relation for UV FeII with the slope consistent with $0.5$ within uncertainties. Since FeII time delay has a shorter time-delay component but lines are narrower than MgII, we propose that the line delay measurement is biased towards the BLR part facing the observer, with the bulk of the Fe II emission may arise from the more distant BLR region, one that is shielded from the observer.Comment: 22 pages, 19 Figures, 6 Tables, Submitted to Astronomy and Astrophysics, Comments are welcom

Wavelength-resolved reverberation mapping of intermediate redshift quasars HE 0413-4031 and HE 0435-4312: Dissecting Mg II, optical Fe II, and UV Fe II emission regions

We present the wavelength-resolved reverberation mapping (RM) of combined MgII and UV FeII broad-line emissions for two intermediate redshifts (z$\sim$1), luminous quasars - HE 0413-4031 and HE 0435-4312, monitored by the SALT and 1-m class telescopes between 2012-2022. Through this technique, we aim to disentangle the Mg II and FeII emission regions and to build a radius-luminosity relation for UV FeII emission, which has so far remained unconstrained. Several methodologies have been applied to constrain the time delays for total MgII and FeII emissions. In addition, this technique is performed to quantify the inflow or outflow of broad-line region gas around the supermassive black hole and to disentangle the emission/emitting regions from lines produced in proximity to each other. The mean total FeII time delay is nearly equal to the mean total Mg II time delay for HE 0435-4312 suggesting a co-spatiality of their emissions. However, in HE 0413-4031, the mean FeII time delay is found to be longer than the mean MgII time delay, suggesting that FeII is produced at longer distances from the black hole. The UV Fe II R-L relation is updated with these two quasars and compared with the optical FeII relation, which suggests that the optical FeII region is located further than the UV FeII by a factor of 1.7-1.9 i.e. $R_{\rm FeII-opt}\sim(1.7-1.9)R_{\rm FeII-UV}$. We detected a weak pattern in the time delay vs. wavelength relation, suggesting that the MgII broad-line originates a bit closer to the SMBH than the UV FeII, however, the difference is not very significant. Comparison of MgII, UV, and optical FeII R-L relations suggests that the difference may be larger for lower-luminosity sources, possibly with the MgII emission originating further from the SMBH. In the future, more RM data will be acquired to put better constraints on these trends, in particular the UV FeII R-L relation.Comment: 24 pages, 16 figures, 5 tables, Accepted for publication in A&A, in Pres

The Influence of the Post-isometric Relaxation Technique of the Iliopsoas Muscle on the Functional Abbreviation of the Lower Limb. Case Study.

The influence of the post-isometric relaxation technique of the iliopsoas muscle on the functional abbreviation of the lower limb. Case study.IntroductionLeg length discrepancy (LLD) is an effect often described in the literature as uneven lengthof the lower limbs. It covers about 40-70% of the population and can exceed 2 cm of inequality in nearly 0.1%.MethodyMaterial/Methody A woman of 40 years with a functional leg abbreviation (LLD), for a period of 6 weeks performed the technique of post-isometric relaxation of the hip-lumbar muscle.

What is the duration of the leg extension?Conclusion:1.Unfortunately, the effect lasted up to two days after 6 weeks of therapy, after 2 days there was a return from before the therapy2. The effect of hip-lumbar pir gave effects but unfortunately not permanen

The Relationships Between Somatic Constitution, Physical Fitness, School Achievements and Fish Products Consumption in Junior Male and Female High School Students

Easily digestible and low-calorie fish products are important components of a proper human diet. The main aim of the study was to assess the relationship between somatic constitution, physical fitness and school grades and the consumption of fish products by junior high school students .  The research was carried out at Junior High Schools No. 8 and 9 in Rzeszów, in the school year 2014/2015. The mean age of examined girls was 13.96 ± 0.26, and boys - 13.97 ± 0.31 years. 118 students (58 girls and 60 boys) participated in the study. Basic somatic parameters were measured and tests concerning motor skills from the Eurofit test were performed. A short survey on the consumption of fish products by students was conducted and information on the results of junior high school final exams were obtained. The research showed that boys who have not consumed any fish products or had them rarely in their diet featured a taller body height. The opposite phenomenon was observed in the population of girls. In the group of boys, better exam results in selected subjects were achieved by those consuming fish less often, i.e. once a week or not at all. In the case of the females this phenomenon is only observed in relation to the exam in the school subject called Nature. The analysis of variance carried out in terms of the frequency of fish consumption showed that depending on the amount of fish products in the respondents' diet, the gender significantly differentiates the level of physical fitness of examined girls and boys (except for tapping)

How to Improve the Efficiency of Our Brain?

The efficiency of the brain greatly contributes to a person's intelligence quotient (IQ), which may ultimately affect one's social status. Neurophysiological processes and IQ change during a person's lifetime and depend on a number of factors, including fluid and crystalized intelligence, diet, physical activity and sleep. As described in the literature, the level of fluid intelligence decreases with age. This process can be delayed by implementing mental exercises and physical factors in one's lifestyle. The SOMECO concept developed in Germany and described in this paper emphasizes the importance of following the most current scientific research in maintaining overall mental health
