In fact, <\/span>the farther away a galaxy is, the faster it recedes<\/b>. This provided the first key evidence that the universe is expanding. But since the universe is permeated by gravity, a force that pulls matter together, astronomers expected the expansion would slow down over time.<\/span><\/p>\n Then, in 1998, two independent teams of cosmologists used distant supernovae to discover that <\/span>the universe\u2019s expansion is accelerating <\/b>rather than slowing. To explain these observations, they proposed a new kind of energy that is responsible for driving the universe\u2019s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up about 70% of the mass-energy density of the universe. Yet, we still know very little about it.\u00a0<\/span><\/p>\n In the following years, scientists began devising experiments to study dark energy, including the Dark Energy Survey. Spain was the first international partner to join the United States in founding the DES project in 2005 and participates through three institutions: the ICE-CSIC, with IEEC researchers, the <\/span>Institut de F\u00edsica d\u2019Altes Energies<\/span><\/a> (IFAE) and the <\/span>Centro de Investigaciones Energ\u00e9ticas, Medioambientales y Tecnol\u00f3gicas<\/span><\/a> (CIEMAT), as well as with researchers from the <\/span>Instituto de F\u00edsica Te\u00f3rica<\/span><\/a> (IFT\/CSIC-UAM). Today, DES is an international\u00a0collaboration\u00a0of over 400 astrophysicists and scientists from 35 institutions in seven countries led by the U.S. Department of Energy\u2019s <\/span>Fermi National Accelerator Laboratory<\/span><\/a>.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text module_class=”section-title” _builder_version=”4.27.5″ _module_preset=”default” header_2_font=”|700|||||||” header_2_font_size=”25px” hover_enabled=”0″ header_2_font_size_tablet=”23px” header_2_font_size_phone=”23px” header_2_font_size_last_edited=”on|phone” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.27.5″ _module_preset=”default” link_font=”|700|||on||||” hover_enabled=”0″ locked=”off” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n To study dark energy, the DES collaboration carried out a deep, wide-area survey of the sky from 2013 to 2019. The DES collaboration built an extremely sensitive 570-megapixel digital camera, DECam, and installed it on the U.S. National Science Foundation V\u00edctor M. Blanco 4-meter telescope at the NSF Cerro Tololo Inter-American Observatory in the Chilean Andes. For 758 nights over six years, <\/span>the DES collaboration recorded information from 669 million galaxies that are billions of light-years from Earth<\/b>, covering an eighth of the sky. Spanish institutions, in addition to making major contributions to the design, construction, testing and installation of DECam and to data taking, currently hold important responsibilities in the scientific exploitation of the data.<\/span><\/p>\n \u201cFrom our images, we can measure galaxy shapes and the subtle distortions caused by gravity, as well as the positions of galaxies and how they cluster across the sky. To interpret these measurements, however, we also need to know how far away the galaxies are. In practice, we infer these distances from their colours, measured through observations in different filters,\u201d says William d\u2019Assignies Doumerg, a doctoral student at the Institut de F\u00edsica d\u2019Altes Energies (IFAE) and a member of the Dark Energy Survey redshift calibration team.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.5″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n \u201cIn this analysis, we have taken distance calibration to an unprecedented level of precision, allowing us to reliably connect the observed distribution of galaxies with the underlying physics of dark energy,\u201d says Giulia Giannini, co-lead of the DES Redshift Working Group and a researcher at ICE-CSIC in Barcelona.<\/span><\/p>\n For the latest results, DES scientists greatly advanced methods using weak lensing to <\/span>robustly reconstruct the distribution of matter in the universe<\/b>. They did this by measuring the probability of two galaxies being a certain distance apart and the probability that they are also distorted similarly by weak lensing. By reconstructing the matter distribution over 6 billion years of cosmic history, these measurements of weak lensing and galaxy distribution tell scientists how much dark energy and dark matter there is at each moment.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/www.ieec.cat\/wp-content\/uploads\/2026\/01\/12-0331-01D.jpg” _builder_version=”4.27.5″ _module_preset=”default” custom_margin=”||2px|||” global_colors_info=”{}”][\/et_pb_image][et_pb_text module_class=”ieec-img-footer” _builder_version=”4.27.5″ _module_preset=”default” text_font=”||||||||” text_font_size=”15px” text_line_height=”1.1em” background_color=”rgba(64,111,218,0.15)” custom_margin=”0px||||false|false” custom_padding=”30px|20px|30px|20px|true|true” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n The DES collaboration built the DECam digital camera, with 570 megapixels and high sensitivity, with a significant contribution from Spanish institutions. <\/span>Reidar Hahn, Fermilab<\/b><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.5″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n \u201cThe final DES lensing measurement includes around 150 million galaxies, an extraordinarily large data set. This is exciting, but it also brings a real responsibility to make sure that every part of the analysis is robust. In DES, we believe we have risen to that challenge. Through new methodologies and strong scientific results, the collaboration has delivered a measurement that will stand as a milestone for many years, and one that we can be genuinely proud of,\u201d says Simon Samuroff, a postdoctoral researcher at IFAE, who co-led the cosmic shear analysis presented in these results.<\/span><\/p>\n In this analysis, DES tested their data against two models of the universe: the currently accepted standard model of cosmology\u2014Lambda cold dark matter (\u039bCDM)\u2014in which the dark energy density is constant, and an extended model in which the dark energy density evolves over time\u2014<\/span>w<\/span><\/i>CDM. DES found that <\/span>their data mostly aligned with the standard model of cosmology<\/b>. Their data also fit the evolving dark energy model, but no better than they fit the standard model.\u00a0<\/span><\/p>\n However, one parameter is still off. Based on measurements of the early universe, both the standard and evolving dark energy models predict how matter in the universe clusters at later times\u2014times probed by surveys like DES. In previous analyses, galaxy clustering was found to be different from what was predicted. When DES added the most recent data, that gap widened, but not yet to the point of certainty that the standard model of cosmology is incorrect. The difference persisted even when DES combined their data with those of other experiments.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text module_class=”section-title” _builder_version=”4.27.5″ _module_preset=”default” header_2_font=”|700|||||||” header_2_font_size=”25px” hover_enabled=”0″ header_2_font_size_tablet=”23px” header_2_font_size_phone=”23px” header_2_font_size_last_edited=”on|phone” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.27.5″ _module_preset=”default” link_font=”|700|||on||||” hover_enabled=”0″ locked=”off” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n \u201cThe Dark Energy Survey is a success story for Spanish cosmology.
