Compressing the cosmological information in one-dimensional correlations of the Lyman- forest
Observations of the Lyman- (Ly) forest from spectroscopic
surveys such as BOSS/eBOSS, or the ongoing DESI, offer a unique window to study
the growth of structure on megaparsec scales. Interpretation of these
measurements is a complicated task, requiring hydrodynamical simulations to
model and marginalise over the thermal and ionisation state of the
intergalactic medium. This complexity has limited the use of Ly
clustering measurements in joint cosmological analyses. In this work we show
that the cosmological information content of the 1D power spectrum
() of the Ly forest can be compressed into a simple
two-parameter likelihood without any significant loss of constraining power. We
simulate measurements from DESI using hydrodynamical
simulations and show that the compressed likelihood is model independent and
lossless, recovering unbiased results even in the presence of massive neutrinos
or running of the primordial power spectrum.Comment: Submitted to ApJ. 17 pages, 7 figure

Exploring the independent association of employment status to cancer survivors’ health-related quality of life
Background: Having a job has been associated with better Health-Related Quality of Life (HRQOL) in cancer survivors. However, the sociodemographic and disease-related profiles characterizing the survivors being employed and those having better HRQOL largely overlap. The present study aims to discern the degree to which employment status is independently associated with cancer survivors' HRQOL or if it mainly reflects the impact of other sociodemographic and cancer-related variables.
Methods: Cross-sectional study on a heterogeneous sample of 772 working-age survivors of adult-onset cancer. An instrument specifically designed to assess HRQOL in cancer survivors and Multivariate Variance Analysis (MANOVA) were used.
Results: Survival phase, cancer type, and employment status showed the main effects on cancer survivors' HRQOL. In particular, being employed (vs unemployed) had the greatest positive association with HRQOL, affecting ten of the twelve HRQOL domains considered. Also, interaction effects highlighted the role of age (younger) and marital status (single) as risk factors for a greater negative impact of variables affecting the survivor's HRQOL.
Conclusions: The application of a multivariate methodology sheds new light on two relevant issues for the cancer survivor's HRQOL: (i) the existence of differences between diagnostic groups that are not attributed to other variables such as sex, and (ii) the important and independent role that employment status plays. Comprehensive cancer survivorship care should focus more on high-risk groups and include having a job as an essential aspect to consider and prompt. The fact that the employment status is susceptible to change represents a valuable opportunity to care for the wellbeing of this population
