This type of kinetically mixed dark matter can be probed in direct detection experiments.
However, we also show that in order to fully exploit the potential of eROSITA for dark matter searches, it is vital to overcome the shot-noise limitations inherent to galaxy catalogues as tracers for the dark matter distribution.
Within this framework, many new models for multi-component dark matter can be implemented.
This suppresses the rate at direct detection searches and thus alleviates the constraints on Z′-mediated dark matter relic abundance.
We also show that the SDSS data provide a strong constraint on the shape of the dark matter halo potential.

Why does first love is more powerful in everone's life?
10 answers
The phenomenon of first love holds a unique and powerful place in an individual's life, often remembered with a vividness that outlasts other relationships. This can be attributed to several factors explored across various contexts. Nancy Kulish emphasizes that first loves during adolescence are not merely reducible to preoedipal or oedipal meanings but are significant experiences that reverberate into adulthood, suggesting a deep psychological impact that shapes future emotional and relational landscapes. This idea is complemented by the abstract notion that love, while not unique, becomes singular and irreplaceable when associated with the first lover, highlighting the unmatched emotional depth and demand the first love experience commands in one's heart. The intensity and novelty of first love experiences contribute to their lasting impact. Adolescent processes, including first loves, are marked by intense affects that individuals resist re-experiencing in treatment due to their profound emotional depth. This resistance underscores the powerful, often overwhelming nature of first love, which can set a benchmark for emotional engagement in future relationships. Moreover, the exploration of various scientific and medical research contexts, though not directly related to the psychology of first love, underscores the complexity of human experiences and the multifaceted nature of our responses to them. From the intricate mechanisms underlying diabetic kidney diseaseto the cardiovascular implications of endothelial loss, each piece of research reflects the broader theme of how initial conditions or experiences can have long-lasting effects, analogous to the indelible mark left by first love. In essence, first love is powerful in everyone's life because it is a confluence of intense emotion, novelty, and psychological development during adolescence. It serves as a foundational experience that shapes individuals' expectations and perceptions of love, intimacy, and relationships moving forward.
What are the interesting theories about dark matter and dark energy?
4 answers
Various theories have been proposed regarding dark matter and dark energy. One theory suggests that dark matter is crucial for preventing galaxies from dispersing, while dark energy has an anti-gravity effect, pushing galaxies apart. Another theory posits that the gravitational energy gradient due to the expansion of ordinary matter, rather than dark matter, explains galaxy rotation, and that this gradient also clarifies Type 1a supernovae brightness observations. Additionally, there is a hypothesis that colored relics from the early universe may have evolved into dark matter and dark energy, with research focusing on their emergence from the primordial quark gluon plasma phase after the Big Bang. Furthermore, a study suggests that dark matter and dark energy are properties of gravity, influenced by the nonlinear interactions of gravitational potential fields.
