探索暗能量与暗物质相互作用的证据

Exploring evidence of interaction between dark energy and dark matter

Daniela Grandon, Victor H. Cardenas

摘要:

在这项工作中,我们使用SNIa,$H(z)$,BAO,$f_{gas}$在集群和CMBR的最新观测,约束三个模型显示暗物质和暗能量之间的显式相互作用。特别地,我们使用在$z \simeq 0.32$、$0.57$和$2.34$的BOSS BAO测量,使用对角度和视线BAO尺度的全二维约束。我们发现,使用所有五个观测探针一起,两个相互作用模型显示出积极的证据,在3 $ σ$以上。尽管意义重大,但需要进一步研究来坚定地确立这一说法。

英文摘要:

In this work we use the latest observations on SNIa, $H(z)$, BAO, $f_{gas}$ in clusters and CMBR, to constrain three models showing an explicit interaction between dark matter and dark energy. In particular, we use the BOSS BAO measurements at $z \simeq 0.32$, $0.57$ and $2.34$, using the full 2-dimensional constraints on the angular and line of sight BAO scale. We find that using all five observational probes together, two of the interaction models show positive evidence at more than 3 $ σ$. Although significant, further study is needed to establish this statement firmly.
